Don't send onMultiWindowModeChanged if relaunch activity.

Browse Source 
If an activity is going to do relaunch, send onMultiWindowModeChanged
sounds meaningless since the activity will be destroy and re-create.
To narrow down the scope, this API should only be useful if the
activity want to handle onConfigurationChanged.
