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.
