contrib.auth dependency on contrib.admin

[nail.xx]

Commit #7808 introduced contrib.auth dependency on contrib.admin. It appears if you included django.contrib.auth in INSTALLED_APPS and didn't include django.contrib.admin. If you will try to run tests (manage.py test), you will see 2 test errors:

======================================================================
ERROR: Email is sent if a valid email address is provided for password reset
----------------------------------------------------------------------
Traceback (most recent call last):
  File "D:\Python\django-trunk\django\contrib\auth\tests.py", line 73, in test_email_found
    response = self.client.post('/password_reset/', {'email': 'staffmember@example.com'})
  File "D:\Python\django-trunk\django\test\client.py", line 286, in post
    return self.request(**r)

    response = callback(request, *callback_args, **callback_kwargs)

    t = loader.get_template(email_template_name)
  File "D:\Python\django-trunk\django\template\loader.py", line 80, in get_template
    source, origin = find_template_source(template_name)
  File "D:\Python\django-trunk\django\template\loader.py", line 73, in find_template_source
    raise TemplateDoesNotExist, name
TemplateDoesNotExist: registration/password_reset_email.html

This is because default test templates are in contrib.admin application and the test is in contrib.auth.

If this is expected dependency it should be declared in documentation (​http://www.djangoproject.com/documentation/authentication/). Or dependency should be removed by using separate URL set and separate templates for that tests.
