Recently we relaxed an assertion in the producer state. The assertion trigger when control batch responsible for ending transaction was lost. This should be treated as an error but it is possible as a result of force recovery operation or other situation in which we accept a data loss. This PR adds a check verifying if producer is already in the active transactional producers list when beginning transaction. Previously without the check assertion was triggered.
