Let talkback read People app name on launch

The root cause was that we were effectively doing setTitle(null) in onCreate.

We were replacing the people activity title with an intent extra, even if it's
not set.  Let's just remove this logic entirely because there's no point of
doing this, as the People activity doesn't show the app title.

This intent extra is not public API in ContactsContract, but it was in the
legacy API, so let's still keep ContactsRequest.set/getActivityTitle for now.
It still works for picker activities.
