Fix an issue where bubbles didn't collapse onTaskMovedToFront

I noticed when opening settings while stack is expanded wouldn't
cause the stack to collapse. This was because we skipped the collapse
if the shade was expanded. I don't think there's any reason to be
doing this, I think this was accidentally added during the refactor
to move bubbles into shell.

Test: manual - have bubbles expanded, pull down the shade, tap on
               the settings gear or long press on a tile, ensure that
               when the settings screen opens that the stack collapsed
