MR !1188 : NR_gNB_initial_MIB_fix  
This MR fixes a bug for which the gNB would send an empty MIB in the first frames of execution. This is because MIB is generated every 8 frames but the first MIB wouldn't be generated before frame 8 at the beginning of each run.

MR !1184 : x2_handle_sctp_shutdown
Avoid eNB exiting after gNB tries to reconnect over X2 for NSA
