Fix: only one subscription could be made
Only one subscription could be made and then only one subscriber could receive associated events. As the relationship between events and subscriber is not 1-1 but 1-N, so this was the mistake. Now 1 event is created for N subscriber where before there was 1 event for 1 subscriber and subsequent subscribers could not receive same events than the ones already subscribed.
