There are two things that need to be changed for this to work:
1. Make the isInOverview condition check for any Overview UI (including
the split select state, modal, etc.)
2. Toggle Home All Apps directly, because firing the intent will cause
Launcher to pause and resume before the intent is handled. We
misinterpret the pause as a request to cancel split screen. Since
TaskbarManager has a reference to Launcher, we might as well call the
method directly.
