Incorrect resolving of Routes with too many underscores.

[Blackskyliner]

I migrated a project to Actions, instead of Controllers. (https://github.com/dunglas/DunglasActionBundle)

I now have for example the following Action:

<?php

namespace Vendor\BackendBundle\Action\Dashboard;

use JMS\DiExtraBundle\Annotation as DI;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Vendor\BackendBundle\Action\Traits\ResponseTrait;
use Vendor\BackendBundle\Action\Traits\TwigAwareTrait;

/**
 * Class Index
 *
 * @package Vendor\BackendBundle\Action\Dashboard
 * @DI\Service(autowire=true)
 */
class Index
{
    use ResponseTrait;
    use TwigAwareTrait;

    /**
     * @Route("/")
     */
    public function __invoke()
    {
        return $this->createResponse(
            $this->render('@VendorBackend/Dashboard/index.html.twig')
        );
    }
}

This now gets correctly parsed and resolved within the SF2 Container. So I get the following debug:route output:

[~/path/to/project]$ php app/console debug:route | grep index                                                                                                                                                                                                                                   [sf2]
  _configurator_step                                               ANY      ANY      ANY    /_configurator/step/{index}
  vendor_backend_action_dashboard_index__invoke                       ANY      ANY      ANY    /

And it also gets correctly created within the appDevDebugProjectContainerUrlGenerator:

<?php

use Symfony\Component\Routing\RequestContext;
use Symfony\Component\Routing\Exception\RouteNotFoundException;
use Psr\Log\LoggerInterface;

/**
 * appDevDebugProjectContainerUrlGenerator
 *
 * This class has been auto-generated
 * by the Symfony Routing Component.
 */
class appDevDebugProjectContainerUrlGenerator extends Symfony\Component\Routing\Generator\UrlGenerator
{
    private static $declaredRoutes;

    /**
     * Constructor.
     */
    public function __construct(RequestContext $context, LoggerInterface $logger = null)
    {
        $this->context = $context;
        $this->logger = $logger;
        if (null === self::$declaredRoutes) {
            self::$declaredRoutes = array(
        '_wdt' => array (  0 =>   array (    0 => 'token',  ),  1 =>   array (    '_controller' => 'web_profiler.controller.profiler:toolbarAction',  ),  2 =>   array (  ),  3 =>   array (    0 =>     array (      0 => 'variable',      1 => '/',      2 => '[^/]++',      3 => 'token',    ),    1 =>     array (      0 => 'text',      1 => '/_wdt',    ),  ),  4 =>   array (  ),  5 =>   array (  ),),

        'vendor_backend_action_dashboard_index__invoke' => array (  0 =>   array (  ),  1 =>   array (    '_controller' => 'Vendor\\BackendBundle\\Action\\Dashboard\\Index::__invoke',  ),  2 =>   array (  ),  3 =>   array (    0 =>     array (      0 => 'text',      1 => '/',    ),  ),  4 =>   array (  ),  5 =>   array (  ),),
        }
    }

    public function generate($name, $parameters = array(), $referenceType = self::ABSOLUTE_PATH)
    {
        if (!isset(self::$declaredRoutes[$name])) {
            throw new RouteNotFoundException(sprintf('Unable to generate a URL for the named route "%s" as such route does not exist.', $name));
        }

        list($variables, $defaults, $requirements, $tokens, $hostTokens, $requiredSchemes) = self::$declaredRoutes[$name];

        return $this->doGenerate($variables, $defaults, $requirements, $tokens, $parameters, $name, $referenceType, $hostTokens, $requiredSchemes);
    }
}

But when I now try to autocomplete it it will try to complete it to vendor_backend_action_dashboard_index___invoke - Note the third _ between 'index' and 'invoke'.
As the autocomplete uses the same data as the invalid route intention/check it will also tell me it's an undefined route if I only write it with two underscores. But if I would use the suggestion of the plugin it will error out on calling the application for not knowing such a route.

So my guess would be somehow the __ gets somewhere translated to ___ within the parser...
