The admin user creation form was trying to set the `username` field of the
User model, but that field does not exists for sure in case of a custom
user model.

But this *field* should be referred as `User.USERNAME_FIELD` to fully
support Usual and Custom user models.

I've prepared a pull request associated to it :
