fix: add a check to ensure the MRO is correct

Add a check to ensure the MRO (Method Resolution Order) is correct for classes in
gitlab.v4.objects when doing type-checking.

An example of an incorrect definition:
    class ProjectPipeline(RESTObject, RefreshMixin, ObjectDeleteMixin):
                          ^^^^^^^^^^ This should be at the end.

Correct way would be:
    class ProjectPipeline(RefreshMixin, ObjectDeleteMixin, RESTObject):
                                      Correctly at the end ^^^^^^^^^^

Also fix classes which have the issue.
