Never setting accessibility focus manually

This will result in the focus going to the second from the right task
upon opening Recents. This will be mitigated by implementing in near
future announcements like Task 6 out of 7.

Besides this, due to (presumably) problems external to Launcher, the
focus may stay on Home button or completely disappear upon opening
Recents.
