Use different reorder modes for fail safe before and after Overview

Currently, when recents animation is cancelled from fail safe mechanism,
we put the previous app back to the top. It no longer makes sense when
live tile is in the picture since we don't want the user to see the
previous app being brought up when they turn off and on the phone.

Fixes: 142088072
Test: Turn off and screen and back on. Make sure the user goes back to
home instead of previous app in live tile mode.
