As-Is, Notification unit test sometimes crash on running.

Cause by,
1) When provider unit test running,
it use invalid request information.
this invalid request is not made by stack,
made by inside unit test as uninitialized variables.

2) When consumer was destroyed, task queue was deinitilzed.
but main task thread waitting for mutex unlocking,
when mutex unlock, main thread does not update address of queue.
actually, address of queue is modified,
in this moment, main thread try to reference unmodified queue and crash.

Fixed,
1) Uninitialized variables are initialized.
2) When main thread mutex was unlocked, updating queue.
   Exception handling what data of queue is invalid.
