Fix behavior of BlockingObservable.last

It now throws an IllegalArgumentException instead of returning null if no elements are emitted.

This is based on feedback from @headinthebox confirming this expected behavior:

var xs = Observable.Range(1,0);                       		// empty sequence
int x = xs.Last().Dump();                             		// throws “sequence contains no elements”       RxJava => BlockingObservable.last()
IObservable<int> ys = xs.TakeLast(1).Dump();          // OnCompleted()                                                RxJava => Observable.takeLast(1)
IObservable<int> zs = xs.LastAsync().Dump();          // OnError(“sequence contains no elements”)    RxJava => Observable.last()
