addmodule - incorrectly used 'unassigned' for hosthame/ip-address when ip-address was used

Run into this problem with a customer during a POC setup. I duplicated problem on my system starting with 1um 1pm. Then did an addModule UM2 and it configured UM2 with unassigned as the host-name and ip-address when I enter 'y' in the third argument, which is new for 1.2.5.

Entering the Ip address as the hostname is valid. The new code assumed a host-name would be entered, I assume.

removed module and reran with the argument as n

So it looks like extra code is needed. If user enters 'y' and ip-address for host-name. then just use the ip-address as the host name instead of unassigned for both. Not sure why that was happening
