    Our TestModelsLoaderMixin, while working fine on Django 1.6, had some
problems on modern versions of Django. Models weren't gaining their
correct app labels and were appearing in two apps at once. We also were
attempting to register models that were imported from other modules
(like User, Site, etc.). Along with this, not all state was properly
cleared.

This change fixes the mixin for Django 1.8 and higher. This gives us
compatibility with Django 1.6 and 1.8 through 1.10. It does not support
Django 1.7 (which Djblets will not officially support anyway), due to
issues in Django 1.7 that were fixed in 1.8 involving ManyToManyFields
not being properly created in the database under these conditions.
    
 
    

    





  

    
 
 
    
  
    Unit tests pass on 1.6, 1.8, 1.9, 1.10.

        What I was aiming for (in this and other changes) is to always have a version of each of these imports we can check for, and to keep lintian checkers from complaining. Pyflakes doesn't seem to care, though.
