Launch AppPair live tile when not visible

* End the recents animation and then relaunch as if
from scratch
* We explicitly ignore the anim for end of recents animation
since that will cause the taskbar to quickly show and stash
again, and we know in this case that we'll quickly be launching
right back into an app

Test: Tested w/ live tile + non live,
fullscreen + app pairs
