Don't consider a window as a candidate for the top fullscreen window if it is not going to be a candiate for layout. Also don't consider windows a candidate for layout if their app token is hidden. This fixes a transient state where we are preparing to unhide the window but have not done so yet. Change-Id: Ife5299ffa003c1df1a4f787b7a2809cbf614ec16
