Add after call notification code in InCallUI.

+Add asynchronous call to update inCallHistory boolean variable which
specifies whether the number is in the call history (has previously
called before)
+Add CallHistoryStatus enum and variable to Call object to determine if
the number is present in the call history
+Added SpamCallListListener object which listens for changes in the
CallList
+Update the CallHistoryStatus for the call whenever an incoming call
comes in
+Added 11 tests for new listener
