Fix gNB RA procedures when Msg4 Ack not received

When the gNB does not receive PUCCH with Ack for Msg4 we have to consider Msg4 received by the UE, so we need to apply the CellGroupConfig sent to the UE.
There are two scenarios:
1 - The UE never decoded PDSCH for Msg4, the RA will fail because RA Contention Resolution timer, the UE will come with a new RA with new RRCSetupRequest
2 - The UE decoded PDSCH for Msg4, and if SR does not work and no resources for PUSCH, it will trigger RA with MAC CE C-RNTI in Msg3 (so, gNB must be ready for it)
