Fixing not responsive tiles in split shade

This is one of the fixes for not responsive bottom row of tiles, which makes sure that expanded shade is set properly.
Expanded shade state is ensured by setting mQsExpandImmediate once we start expanding shade. This was set only in startWaitingForOpenPanelGesture and it doesn't cover some gestures (like swiping from the top), so I moved setting mQsExpandImmediate to more generic onTrackingStarted which should be called in more cases when shade starts to expand.

Bug: 228198572
Test: On homescreen expand shade pulling from status bar and see if most bottom row of tiles (when 9 tiles are visible) is functioning correctly
