Florian Müllner 3e8b7faab8 messageTray: Emit signal when notifications are enabled/disabled
Since the introduction of per-source notification policy in commit
098bd4509ba0, the NotificationPolicy::enable-changed signal has been
used to track the 'enable' setting. However as we never actually
emitted that signal, this never worked without a restart - oops.
