Fix stage split rotation

On current implementation, it will use DC.getLastOrientation in
TDA#getOrientation, it will got SCREEN_ORIENTATION_NOSENSOR so it
didn't rotate.

Fix this by adding checking if TDA non floating root task is visible
and creadted by organize, it should all use
SCREEN_ORIENTATION_UNSPECIFIED.
