Recreate icon alignment controller when isIconAlignedWithHotseat changes.

Before: when launching an app and immediately swiping home, the icon alignment
animation would become stale, which lead us to playing the wrong interpolator
for the action key alpha animator.

Fixes: 359579152
Test: open app, then immediately swipe home
Flag: EXEMPT bugfix
