overviewControls: Hide the appDisplay when it's not shown

Browse source 
Hiding actors allows excluding them from layout, so by hidding the
appDisplay in all the cases where the overviewAdjustment is not actually
showing it, we can save a lot of time on the first frame of painting
the overview because we no longer have to layout the whole appGrid.
