Exclude home and recents activity types when overriding recents-excluded tasks

These tasks could point to overview itself, causing a very confusing screenshot. By excluding these tasks, we will default to using the task preview

Flag: NONE bug fix
Fixes: 336334715
Test: used circle to search from home, swiped to home, then pressed "select" overview action button. also checked temp logs
