fix: do not use ended_at from call state to check ringing validity (#…

…1466)

**Behaviour**: 
we should not schedule timeout based rejects if the call had already
ended, as BE will respond with 400

**Background**:
`callState.ended_at` represents the last time the call was ended
`callSession.ended_at` represents if the current call session's ended
time

**Fix:**
we should not schedule timeout based rejects if `callSession.ended_at`
is present and not based on `callState.ended_at`
