/**
* Returns an Observable that emits only the last item emitted by the source Observable.
* It optionally takes a predicate function as a parameter, in which case, rather than emitting
* the last item from the source Observable, the resulting Observable will emit the last item
* from the source Observable that satisfies the predicate.
*
* <img src="./img/last.png" width="100%">
*
* @throws {EmptyError} Delivers an EmptyError to the Observer's `error`
* callback if the Observable completes before any `next` notification was sent.
* @param {function} predicate - The condition any source emitted item has to satisfy.
* @return {Observable} An Observable that emits only the last item satisfying the given condition
* from the source, or an NoSuchElementException if no such items are emitted.
* @throws - Throws if no items that match the predicate are emitted by the source Observable.
