New forum post notification reappears after visiting forum
When the new forum post notification shows posts in multiple forums, touching the notification dismisses it, as expected. (Touching the notification leads to the contact list rather than the forum list, but that's probably adequately covered by #289 already.) When one of the forums is then visited, the notification reappears, showing the new posts in the remaining forums.
(This bug was already marked as a FIXME in AndroidNotificationManagerImpl.)
