Restore old interpolators for Overview -> Home

This regressed due to b/236761067 updating the transition from Split
Select to Home (go to Overview, select an app to enter Split screen, but
then go home instead of picking the second app to split with). Kept the
new interpolators for OVERVIEW_SPLIT_SELECT to home, but restored the
old interpolators for OVERVIEW to home

Test: Manual, watch transition from Overview to Home, and Split Select
to Home
