Comment 1 for bug 1586258

So I couldn't sleep. This patch should solve the problem by bypassing the checks that cause it. Because of the way the rulesets get rebuilt anyway I can't see this causing any problems down the road, but you never know.

I looked at writing a test but couldn't quite figure out how to do it. I did install the modified version into a prefix and test the following possible bug-trigger.

$ PYTHONPATH=$PYTHONPATH:/tmp/ufw/lib/python /tmp/ufw/usr/sbin/ufw insert 1 allow from any to any

and it functioned correctly. The backend changes seem the least invasive way to solve the problem, but I'm not entirely happy with the frontend changes; they may benefit from a more experienced tweak.
