Subject: [PATCH] Prevent duplicated call of |Terminate|

There will be duplicated call of |Terminate| in following case.
When pressing back key multiple times,
h/w key events emit multiple |Terminate| as they are pressed.
The |Terminate| needs to be processed once.

Bug: http://suprem.sec.samsung.net/jira/browse/TWF-2801
