cbc: Expect Concurrent-Warning-Message-Indicator IE in SBcAP Write-Repl-Req

3GPP TS 23.041 9.3.32 states that the IE is always present for non-ETWS
messages and never present in ETWS messages.
The present template is used for CBS messages (non-ETWS) only so far.
Once we add support to test ETWS message this will be updated
accordingly if needed.
