Fixed the navigation bar placement on device restart.

Moved logic that adjusts the hotseat position from the constructor of
the NavbarButtonsViewController to onTaskbarLayoutChange() method that
is called from the TaskbarViewController TaskbarView layout change
listener.

Test: Manual:
Moved the bubble bar to the default right position. Rebooted the device.
Navigation bar was placed on the left side of the screen.
