contrib.auth test fails due to duplicate user

[Ben]

In django.contrib.auth.tests.auth_backends.py we have (line 153)
self.user2 = User.objects.create_user('test2', 'test2@example.com', 'test')
In django.contrib.auth.tests.forms.py we have (line 224)
>>> user = User.objects.create_user('test2', 'tesT@EXAMple.com', 'test')

These usernames clash and an error is raised. The attached patch simply changes the usernames in forms.py.

I'm guessing this problem can only be triggered with certain test ordering, because I can't force the error myself. However, it's a trivial fix, so it warrants correction.

(In [12778]) Fixed #13108 -- Corrected an ambiguity in test data with the potential to cause test failures out of the box. Thanks to benreynwar for the report.
