Now that we're not calling g_object_run_dispose() indirectly in g_test_dbus_down() (see commit "Revert "gtestdbus: Properly close server connections""), the test gdbus-connection-loss is failing with the message "Bail out! GLib-GIO-FATAL-WARNING: Weak notify timeout, object ref_count=1". This is because we're holding a reference to the singleton connection object while calling session_bus_down() in the test's main(). So then we end up waiting for 30 seconds in _g_object_unref_and_wait_weak_notify() for the GWeakNotify to be triggered, which never happens. The fix is to unref the connection before calling session_bus_down(). This is consistent with how other tests work, and is safe because the only method called on the connection has already errored out, as asserted by the test.
