Fixed Double post count decease for delete + thread move

2.2.8 Patch 1
If you delete a thread, and then move it from a forum which counts posts to a forum which does not count posts; users of that thread get their post count updated twice.

This also applies to moving a deleted thread and then undeleting it, at which point the post-count is increased twice over what it should.

The problem is the very first part of Thread::threadMoved;
    protected function threadMoved(Forum $from, Forum $to)
        if (!$this->isStateChanged('discussion_state', 'visible'))
            $newCounts = $to->count_messages;
            $oldCounts = $from->count_messages;
            if ($newCounts != $oldCounts)
                $this->adjustUserMessageCountIfNeeded($newCounts ? 1 : -1, true);

There is no check for the thread's current visibility.
