MultiTable Inherited Model Tests fail with Django 1.11a1

[cdman]

running tox on master I get (I don't have Python 3.4 installed):

ERROR:   py27-djangomaster: commands failed
...
ERROR:   py35-djangomaster: commands failed

For me Django master is at 74a575e: django/django@74a575e

SHA256 for the https://github.com/django/django/archive/master.tar.gz I'm seeing: `bc2874ca4e3bce55f528d4cd4fc9b36a5164313675ad534b8b900502ffe9f79d``

The failing tests are:

Indeed. Needs further investigation. We don't necessarily support running against Django master, as some bits of public & private API may change under our feet, but it's worth having these resolved in anticipation of 1.11.

Any further digging from anyone on this is most welcome.

btw, the django-filter backend is migrating to the django-filter package. Any fixes to IntegrationTestFiltering here should probably have a corresponding PR in django-filter.

To review as part of 3.5, depending on if we deprecate Django filter as part of that release or not.
