When working with multiple AbstractModule inheritance you may
have Class1 and Class2 instanciated:

Class1(Module, CapBank)

Class2(AbstractModule, CapBank) (Abstract of Class1)

Instanciating a class Class2 object, its MRO contains both
Class1 and CapBank.

So when looking for Class2 capabilities, the patched method
as returning Class1 because actually Class1 is a subclass of
Capability as it inherit from Class1.
