Code review comment for lp:~abentley/launchpad/fix-undiverging

Thanks for fixing that—the mistake was mine!

A note about the test: there's a factory.makeDivergedTranslationMessage for creating diverged messages.

About the fix itself: approveSuggestion could be used very intensively, so for performance it may be worth shortcutting the getCurrentTranslation call (which queries the database) in cases where the message is diverged. In those cases, there's no chance of it being shadowed by another diverged message.
