ensure updated config is synced on use of restart command

[zth]

Initial read configuration was never refreshed as the restart command runs, which means you'd always get potentially stale initial config after a restart.

Also clean up a few init things that I suspect has never been cleaned up after the initial adaption of the LS client example.

Looks great.

The only thing that comes to mind, is how to make it completely explicit that the code that follows createLanguageClient is the global state. (which is preserved on restart).

In fact, there's one other small bit of global state:

let client: LanguageClient;

which is followed by a bunch of commented out code. Then the createLanguageClient function. Then the rest of the global state.
