Description
If, in a D-GSM ecosystem, two MSCs are accidentally configured with identical IPA unit names on the GSUP wire,
the first MSC that shows up should continue to work normally, while any later MSC with identical name should be thwarted with OSMO_GSUP_MSGT_E_ROUTING_ERROR responses.
Test that this works as expected, particularly, that there is no way to inadvertently hijack GSUP conversations that are in flight to an MSC with the same name.

tested, and fixed a problem in gsup_server.c so that the ROUTING_ERROR message is indeed sent to the peer that would cause the name collision,
and not the peer that was there first and validly holds the name that the second peer attempts to re-use.
