Fixed an issue where scrolling didn't work anymore after going to landscape

Because of the way linearlayout measures and because we never invalidated
our measure cache, the measuring of the view would be skipped, leading
to issues. We're now forcing the measurement to be invalidated
when changing the measuredState.

Test: use crosshatch, go to expanded qs, have 2 players. Rotate back and forth. Observe normal scrolling
