MSC/SMPP: introduce TC_smpp_mo_sms_rp_error for OS#4351
This test case reproduces the problem described in OS#4351: 1. MS/UE submits a MO SMS which it getting touted to an ESME; 2. MSC prematurely responds with RP-ACK to the MS/UE; 3. ESME responds with DELIVER-SM error; 4. SMS transaction is already terminated (by RP-ACK). Expected behaviour: 1. MS/UE submits a MO SMS which it getting touted to an ESME; 2. ESME responds with DELIVER-SM error; 3. MSC terminates the SMS transaction with RP-ERROR. Change-Id: I33c6ea0ffdf8b8a45f587d690bdceb38fc42c898 Related: OS#4351
