Don't force the download notifier to unbind

The DownloadNotificationService tells the SystemDownloadNotifier to
unbind from it when it has no notifications to show and wants to shut
itself down.  This isn't needed because the SystemDownloadNotifier will
unbind when it is a safe time for the service to die.  This patch
removes the Observer method that tells the SystemDownloadNotifier to
unbind itself.
