	`g_notification_backend_new_default()` adds a reference on `backend->dbus_connection` (if non-`NULL`), but nothing ever unreffed that. Fix that by adding a dispose method. In practice this is not really a problem, because the notification backend is held alive by a `GApplication`, which lives as long as the process. It’ll be a problem if someone is to ever add unit tests for `GNotificationBackend`s though. So let’s fix it. Signed-off-by: Philip Withnall <pwithnall@endlessos.org>
