Test Client logout does not work with cookie-based sessions

[Gunnar Scherf]

The test.client.Client.logout does not clear the cookie.
After calling logout the user is still logged in because of the cookie.

A solution would be to clear the cookies in the logout function like in Django 1.5

self.cookies = SimpleCookie()

With that test added:

diff --git a/tests/test_client/tests.py b/tests/test_client/tests.py

It fails on 1.6 and pass on 1.5.
