I have a custom User model that is exactly the same as Django's default
User model except for the fact that we allow longer usernames (I'm on
Django 1.9, which has a 30 character limit on usernames). Because this is
the only difference, I use all default User models in the Admin. However,
when I try to create a user with a long username, I get the 30 character
limit error. In the shell everything works fine. When investigating I saw
that in the `django/contrib/auth/forms.py` file, the `UserCreationForm`
referred to `django.contrib.auth.models.User`. I believe it should refer
instead to `UserModel` (which is declared in the file using
`get_user_model()`).
