skip IP address when hostname-for-clients has been provided

for cases where client-bind-address is an internal IP address (behind a firewall) or 0.0.0.0 etc, then adding the IP address to hostname-for-clients specified value can result in incorrect client behaviour, so skip adding IP address for such cases updated FabricServerTest for the above change
