[r=abentley][no-qa] Remove workaround for Twisted bug that has since been fixed upstream.

This branch cleans up a work-around for a problem that has been fixed upstream, http://tm.tl/2518. In the branch I had also tried to remove what looked like an old work-around from a Bazaar upgrade, but that didn't work out. You can see the legacy of that attempt in the moved helper method and the updated comment.
