Forward showing desktop only to rootInfo if it changed 

Summary:
There was a property change for whenever a window gets activated although
that doesn't change the state.

In addition a nullptr check for rootInfo is added for the future no
XWayland case.

Test Plan:
run xev -root to verify the property does not get updated
needlessly
