C5G: Release UE Context before sending Service request
A recent fix in Open5GS rejects RAN_UE_NGAP_ID in InitialUEMessage. This
causes all tests to fail that send a subsequent InitialUEMessage with
the same RAN_UE_NGAP_ID.
Release the UE Context before re-using the RAN_UE_NGAP_ID, because the
connection handler can only handle one context at a time.
Note that the AMF_UE_NGAP_ID is incremented by Open5GS for every
context.
This fixes:
TC_ue_service_request_cm_idle_inact_sess
TC_ue_service_request_cm_idle_ul_data
TC_ue_service_request_cm_idle_unknown_sess_active
