[dw-free] clean up error logs

[fu]

[commit: http://hg.dwscoalition.org/dw-free/rev/c90874268293]

http://bugs.dwscoalition.org/show_bug.cgi?id=2812

Be more lax when checking whether the topicurl from the subscription matches
that in the DB. Account for escaping and make the match case insensitive.
