Fix logic around launchTask in the live tile case

When how things are structured changed in the past 1-2 releases, we have dup logic in launchTask. There are two cases
- Swipe down from Overview: RecentsView#createTaskLaunchAnimation. In endListener, call launchTask in the non live tile case, and call finishRecentsAnimation in the live tile case
- Tap on the TaskView to launch task: In the non live tile case, call launchTask as it calls startActivity with option. In the live tile, currently we call createLaunchAnimationForRunningTask, which plays the task launch animation, which calls finishRecentsAnimation at the end. But this animation is not sufficient, when the user swipes the live tile task off to the right and tries to launch it. We will need to replace this animation with createRecentsWindowAnimator
