docs: /*
  If the caller prepared the add of an active message they must come back
  with either a commit or rollback of that prepare.
  
  This method rolls back the add of the active message, i.e a message wasn't
  locked to the consumer
  
  NOTE: Callers to this method will still have the JSLocalConsumerPoint locked
  since the prepare
