Fails to deliver topic to all subscribers if one throws (v3.5.0)

[georapbox]

Consider the following example:

const pubsub = PubSub();

pubsub.subscribe('MY_TOPIC', () => {
  throw new Error('Oooops!!!');
});

pubsub.subscribe('MY_TOPIC', data => {
  console.log('Won\'t enter here');
});

pubsub.publish('MY_TOPIC');

If first subscriber throws, then PubSub fails to deliver the topic to the second subscriber.
