Tests brake after each 2nd run

[benste]

Running

python manage.py test

the first run is fine - all following attempt will fail - i assume our testing mailman instance is somehow shut down.

e.g.
File "/home/benste/Projects/Mailman/mailmanweb/src/mailman_django/tests/__init__.py", line 250, in mailman_django.tests.__test__.Doctest

    response = c.get(url)
