SystemUI: fix RecentPanel position in landscape mode.

In landscape mdoe we forcing ltr layout direction. This cause
call to resolvePadding too late and discards paddings
computed by fitSystemWindows. To workaround this we can catch
onRtlPropertiesChanged and force executuin of fitSystemWindows
one more time. To fix scroll issue after padding will be setted
we calling scrollTo with correct position.
