version and group are lost when generic invoker,Impact Dubbo version 2.7.3

[ningyu1]

• I have searched the issues of this repository and believe that this is not a duplicate.
• I have checked the FAQ of this repository and believe that this is not a duplicate.

Environment

• Dubbo version: 2.7.3
• Operating System version: Win7
• Java version: 1.8

Steps to reproduce this issue

1. Generic invoke

ApplicationConfig application = new ApplicationConfig();
application.setName("api-generic-consumer");
ReferenceConfig<GenericService> reference = new ReferenceConfig<>();
reference.setUrl("dubbo://ip:port/com.xxx.XXXService");
reference.setVersion("1.0.0");
reference.setGeneric(true);
reference.setApplication(application);
reference.setInterface("com.xxx.XXXService");
GenericService genericService = reference.get();
Object obj = genericService.$invoke("getYYY", new String[]{Long.class.getName()}, new Long[]{1L});
String json = JsonUtils.toJson(obj);
System.out.println(json);

2. ReferenceConfig.init() -> ReferenceConfig.createProxy() -> ClusterUtils.mergeUrl(), Lost after passing 'ClusterUtils.mergeUrl'.

ps. Dubbo v2.7.2 previous version verified that it will not be lost.
