Care the case of no registered event handler.submit/tizen_2.2/20130717.053124submit/tizen_2.2/20130716.1732482.2_release

If a provider developer didn't register the buffer type event handler,
accessibility should send back its status to the client.

If it doesn't send it, the client will be stuck for waiting it.
