ASCI: Allow incoming VGCS/VBS connections at RAN_Emulation.ttcnpp 

Similar to Handover Requests the RAN Emulation can accept new SCCP
connections with VGCS/VBS Setup message and VGCS/VBS Assignment Request
message. The point code for the incoming connection can be registered
in the same way as for the Handover Request.

In order to allow multiple connections with the same point code, the
table entry in the ExpectTable must be released after receiving the
message. VGCS/VBS calls have multiple connections to the same BSC.
This patch does not break existing MSC handover tests.
