Remove calling signal finalization

Sometimes, the app process is deadlock while calling the g_object_unref().
While calling fork(), gdbus thread of the parent process has a mutex
locked. In the child, the mutex is in the locked state.
(locked by a nonexistent thread and thus can never be unlocked.)
