Handle onBindingDied in notification manager

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
