fb: correct the google animation on flipping to QS to be nicer

that the carrier text on flipping to qs hides when QS is already present
is not very nice from UX perspective. Correct this behaviour to hide
it directly when the user goes into QS. Same for notification shortcuts

As well reflect this behaviour on manual flippsettings
