Hide DesktopTaskView background while animating 

While animating DesktopTaskView to/from fullscreen, hide the background.
Background should only show up when this taskview is shown in recents.
While it is animating, we don't need to show it.

Bug: 263264985
Test: manual, trigger transient taskbar, observe that background does
not flicker
