Run animation for liveTile before trying to launch it

* If current TaskView is running live tiles, animate directly
when toggling recents button instead of trying to
launch the task

Fixes: 240231324
Test: Launching a single GroupedTaskView from overview
launches as expected in 3 button.
Tested adjacent launches as well.
