Change in method prototype logic since 7.0.6

There was a change in Reflection prototype logic, see https://3v4l.org/LLebD

```
Method [ <user, prototype Go\ParserReflection\Stub\InterfaceWithMethod> public method foo ] {
  @@ H:\Work\parser-reflection\tests\Stub\FileWithClasses55.php 150 - 150
}

Method [ <user> public method foo ] {
  @@ H:\Work\parser-reflection\tests\Stub\FileWithClasses55.php 150 - 150
}
```
