Only call reset() when transitioning to a State that doesn't have RecentView visible

- Changes to BaseRecentsViewStateController/FallbackRecentsStateController to avoid calling reset when canceling transitioniong to a RecentsView visible state (e.g. canceling Overivew -> OverivewModal)
- Changes to LauncherRecentsView/FallbackRecentsView to have a consistent check in deciding if we should reset on transition finished
- Note: With 3P Launcher, there is an existing issue that isn't fix by this change: While in Overview or Split select, tap empty space to dismiss Recentsview, then immediately swipe up, Overview tiles will be blank. This is because the swipe up isn't a "brand new" gesture and doesn't call onGestureAnimationStart, so it does not reload thumbnails after the reset in animation cancels.

Test: Reproduction steps in b/246232494, b/243471493, b/242715097 and b/359872614
Test: Trasitionoing between Normal,Hint,Overview,OverivewModal,QuickSwitch etc., and which Home/Back gesture in between to cancel the transitions; repeat the test with 3P Launcher
