Cleanup taskbar+assistant interactions
- Always move the taskbar layer when voice interaction window visibility
changes, to ensure we remove the temporary taskbar background in all
cases (e.g. swipe to home)
- Move check to not draw taskbar background to the temporary view
itself, so that it's at the proper layer when shown (e.g. during
fulfillment on the home screen)
- Don't add view to window if it's already added (we already have this
check for the removal case)
Test: Open an app, invoke Assistant, swipe home; Taskbar background is
removed; invoke and fulfill assistant from home screen, in app, in 3
button mode, and in gesture mode (all permutations)
