Duplicate class names causes QMetaObject misbehavior

When a Python class has the same name as one of its base classes, its Signals are not properly installed on its QMetaObject.  Taking the example from the bottom of https://wiki.qt.io/Qt_for_Python_Signals_and_Slots, injecting a base class also named 'Communicate', and adding a second signal+slot causes warnings like this...

Signals and slots in QMetaObject 'Communicate' are not ordered correctly, this may lead to issues.

...and the second slot cannot be triggered.  See the attached file for the full example.

If the classes are given different names (e.g. 'Base' and 'Child'), then both slots are triggered and no warnings are emitted.

This is a change in behavior since PySide 5.11.2.
