Do not play unstash animation when unlocking the device

The unstash is ignored by TaskbarStashController, while the TaskbarLauncherStateController positions the hotseat on the launcher correctly without animation.

Since the TaskbarStashController is used even with 3p launchers, both of these actors keep track of whether the device is locked independently, based on the SysUI flags.
