Discover tests in Django 1.6
Discover tests in Django 1.6

Django's test runner changed in Django 1.6, and the way tests
were discovered changed as well.  Consequently
`call_command('test', 'bakery')` won't work for Django >= 1.6.

Set the test module name to `baker.tests` in more recent versions
of Django so the tests will get discovered.
