Code review comment for lp:~gmb/launchpad/ubuntu-filebug-dupefinder-bug-497096

This branch fixes bug 497096 by moving the Ubuntu +filebug redirect code into FileBugGuidedView, which is where it actually gets used. This means that sundry +filebug views (+filebug-inline-form, +filebug-show-similar and so on) shouldn't redirect, which means that the inline dupe finder will now work.

You can QA this on lp.dev by setting ubuntu_disable_filebug to True in configs/development/launchpad-lazr.conf and hitting ubuntu/+filebug with ?no-redirect=1 in the query string. The dupe finder should Just Work.
