        We need to fix the include() logic for admin URLs. Django admin isn't
        very extensible, so we have to call super, remove the url patterns

        a properly built include behind the model admin's gate.

        Would be a lot easier if django exposed something like
        get_patterns_for_app(app_label), but noooooo.
