Re-enable remote occlude/unocclude animations.

This was previously disabled due to an issue where the bouncer would
appear whenever the home controls (or other non-camera occluding
activites) were launched. This issue appears to now be fixed on
tm-dev, likely by some of our other fixes over the last month.
