Restarting the child actor means resetting its behavior to the initial
one that was provided during its creation (i.e. the one which was passed
into the Props constructor). The previously failed behavior will
receive a PreRestart signal before this happens and the replacement
behavior will receive a PostRestart signal afterwards.
