Admin login form is broken

[igloox]

On Django 1.8, trying to log in using the admin login form fails. EmailAdminAuthenticationForm.clean() tries to call self.check_for_test_cookie(), which raises an error::

AttributeError: 'EmailAdminAuthenticationForm' object has no attribute 'check_for_test_cookie'

The EmailAuthenticationForm.clean() method checks if the method exists using hasattr before attempting to call it - I presume the EmailAdminAuthenticationForm should do the same?

@igloox Thanks for the bug report, it will be ok on the next pypi version.
