tentative working Django 1.7.1 (bug 935538)

* wip don't merge
* removed funfactory and test_utils

- [x] tests seem a bit slower, mocking might be failing
- [x] need to check on the django-tastypie pinning
- [x] need to run baked
In both cases for me `test` is at `sys.argv[1]`, which I think is consistent with the docs at https://docs.python.org/2/library/sys.html
