* TEST: enabled testRetainAll

* Method resolution spared of annotations and generics

* TEST: test for canonical names "interface+generic" added

* Methods' canonical names support:

- Recursive iteration of method argument types
- Arguments in question are delivered from topmost overriden ancestor of this method
