MSC_Tests: do not send an SGsAP-MO-CSFB-INDICATION when testing MT-Call

The TTCN3 tests MSC_Tests.TC_bssap_lu_sgsap_lu_and_mt_call and
MSC_Tests.TC_sgsap_lu_and_mt_call initate an MT-CSFB call for testing
purposes, but they also send an SGsAP-MO-CSFB-INDICATION to make the MS
come back to LTE. This is wrong. SGsAP-MO-CSFB-INDICATION just informs
the VLR that the UE has initiated a MO CSFB call on the LTE side. On MT
CSFB calls this message should not appear. Lets remove it.
