FAB-694: Allow docker name to be picked up

Workaround for issue with docker-compose returning the
service name instead of the container name. This behavior is
sporatic, so this workaround allows for the correct selection
of the desired container regardless of which value is returned
when stopping and starting a peer using 'docker stop/start'.
