What happens:
At the moment, every time checkwatches is run against the Gnome Bugzilla, a check is made to see whether a given bug watch is against a Gnome product for which we sync comments (this will always be False, at the moment, since there aren't any such products). If the product is one we should sync, the watch is assigned to an instance of the BugzillaAPI ebt. If not, it is assigned to an instance of the Bugzilla ebt.
What should happen:
The Gnome Bugzilla uses Bugzilla 3.4, so both instances returned by _getEExternalBugTrackersAndWatches() should be of the BugzillaAPI class. The ones that we don't want to sync comments for should have sync_comments set to False. It's important that we land this before we start to add products to our list of products-to-sync.
