Code review comment for lp:~intellectronica/launchpad/no-patches-message

(See bug #506018 for more on what the "+patches" view does.)

To test this branch, apply this diff to database/sample/current-dev.sql:

  http://people.canonical.com/~kfogel/patches-view/patches-view-current-dev-sql.diff.gz

Then do 'make schema' and 'make run', and visit:

  https://bugs.launchpad.dev/ubuntu/warty/+patches

You should see an infobox message saying:

  "There are no patches associated with Warty at this time."

But if you visit other URLs, like these...

  https://bugs.launchpad.dev/ubuntu/hoary/+patches
  https://bugs.launchpad.dev/patches-view-test/+patches

...you will see patches listed.
