Correctly initialize RLC when using phy-test mode

When using phy-test mode, the RNTI for PDCP/RLC initialization would be
0, incorrectly initializing these layers, fixed in this commit.

Additionally, in this commit, we only trigger the initialization in
cases where the UE context is initialized (before, the RNTI might be 0
in other cases as well).
