Code review comment for lp:~lifeless/launchpad/edge

Given we aren't replacing parts of the url any more, we can simplify the following:

   uri = URI(canonical_url(bug.default_bugtask))
   # Empty the traversal stack, since we're redirecting.
   self.request.setTraversalStack([])
   # And perform a temporary redirect.
   return RedirectionView(str(uri), self.request, status=303)

to just be

   # Empty the traversal stack, since we're redirecting.
   self.request.setTraversalStack([])
   # And perform a temporary redirect.
   return RedirectionView(canonical_url(bug.default_bugtask), self.request, status=303)

But on the whole, it looks fine.
