requested review from @schmidtr

just write 12000 ms is arbitrary and found to be a good timeout from experiments or something like that

Review by @schmidtr

Recommendations:

• minor comment, TODO is confusing, accepted apart from that
• the test RAN-gNB-nrUE-MONO-TDD-Band78-N300 fails because of segfault. The timer seems to be triggered although there is no RA. You can easily reproduce this on any machine with the below command.

• RAN-CI-develop failed because of CI problem (it seems), I wait for confirmation by @defosseu then will retrigger
