Should we add a log here if there are multiple event listeners?

Adding a log message here, is not a good convention. What I could do is add an assert, that invoker of this method expects no more than one eventlistener. But that has consequences, if people are upgrading.

Thanks @ScrapCodes. Have a small nit, and also please address Auden's comments. Otherwise it looks good.

Nit : Change variable name to eventListeners
A previous PR added the needed changes to support Multiple event listener. However it missed some changes in tests, query runners etc. So here we fix the follow up, i.e. fix tests etc..

I think this should be Optional<List

Thanks @jaystarshot for taking a look. I am not fully sure, I understand that. List can have zero elements (an List#isEmpty check similar to Optional#isPresent check), and if we are concerned about not breaking existing users, we added a default Optional<EventListener> in QueryRunner interface Link.
