medmunds 8db86a8274 Fix RuntimeError on sys.modules in reset_warning_registry ...

Django 1.8's reset_warning_registry (which we backport)
was generating `RuntimeError: dictionary changed size
during iteration` in Travis tests under Python 3.x.

Likely a thread-safety issue on sys.modules.values().
See https://code.djangoproject.com/ticket/21049
for fix applied elsewhere in Django.
