TypeProviders break complex signatures

[MaXal]

Function reference may have signature like #M#C\Foo.get|#M#C\Bar.get. For this case, the method fr.adrienbrault.idea.symfony2plugin.util.PhpTypeProviderUtil#getReferenceSignatureByFirstParameter won't work correctly as well as all providers that call it since they transform the signature into #Ő#M#C\Foo.get|#M#C\Bar.getƂparamValue instead of #Ő#M#C\Foo.getƂparamValue|#Ő#M#C\Bar.getƂparamValue.

The consequence of the bug is the following exceptions and broken functionality of plugin:

Unfortunately, we were unable to foresee this when designing getSignatureAPI and everyone have to deal with this manually...

When namespaces were introduced to PHP it became so that for any non-fully-qualified function ref its signature is always #F/local/namespace/funName|#F/funName plus some more cases arise...
