Handling Launcher configuration change between touchDown and Launcher.onStart

is running leading to inconsistencies between deviceProfile and rotation
> Using activity configuration to determine the rotation instead of using display rotation
> Removing rotation watcher when rotation is enabled as it is not used anymore
