Code review comment for lp:~jml/launchpad/fix-release-hot-bugs-486437

As the linked bug indicates, the "Bugs" tab page for a project (or any bugtarget, really) shows "Fix released" bugs on the "Hot bugs" area. This really sucks, especially for small projects, since "Fix released" bugs aren't really interesting in active development.

This patch changes the search used for the "Hot bugs" table such that it only shows unresolved bugs. I haven't added a test, because I can't see any place that has already been established for such a test to go.
