There was some repetitive logics that validated the existence of
eventlisteners. We now replace this with a single line of,
`hasEventListener(self, type)`.
`self` is the object(e.g. EventEmitter) to be checked whether
eventlisteners exists or not.
`type` is the type of eventlisteners, which can be `undefined`
