Support inherited static functions

[letynsoft]

When the resolveScopedPropertyAccessExpressionNodeToFqn cannot find the definition, try it the extended class

[letynsoft]

Hmm, from the tests it really doesn't like that, but from the functionality it works nice :-(
Is there any way to do this only when this is request from the editor?
They doesn't seem to be added for a right reason in the tests...

Could you explain what this PR fixes? What do you mean with parent contexts?

[letynsoft]

eg.

class a {
  static function a () { ... }
}
class b extends a {
}

and then when you call b::a() the language server is able to find the method then (same as PHP does)

[felixfbecker]

There is a lot of logic here that does not change on each loop iteration, such as the instanceof checks above and the member name. Could you save this in variables and move it out of the loop?

[felixfbecker]

Also, could you add a test?

Hi,
The standard TestClass method and variable finds the reference to the call/access, so i think that is what i can test there :)
