Handle onBindingDied in notification manager

On Android, if the process containing the service being bound to
crashes before the bind succeeds, the app doing the binding won't
get a success or failure callback.

When that happens in this code, this leaves notif. manager thinking
that a binding is in progress, so it never attempts to rebind until
the device is rebooted.

Bug: 69064494
Test: manual, crashed listener on proc start, verified not unbound forever
