Bring home to front behind assistant stack when needed.
It is possible to return to an assistant stack over stack other
than the home stack despite starting over it. This can happen when
the assistant activity launches an activity in another stack, such as
the fullscreen stack. We were previously assuming that the stack
underneath would stay static and therefore did not account for the
another stack coming on top.
This CL addresses the issue by recognizing when home was below the
assistant stack and ensures that it is brought forward before
bringing the assistant stack forward
