Have UnsubscriptionError log something nicer to console

[benlesh]

RxJS version: 5.0.0-beta.5

Code to reproduce:

const source1 = Observable.create(() => () => { throw new Error('I am an error'); });
const source2 = Observable.timer(1000);
const source3 = Observable.create(() => () => { throw new Error('I am another error'); });
const source = source1.merge(source2, source3);

const subscription = source.subscribe();

subscription.unsubscribe();

Expected behavior:

Console logs out something readable to the effect of UnsubscriptionError: 1) Error: I am an error 2) Error: I am another error.

Actual behavior:

Console only logs out UnsubscriptionError. User is expect to catch it an analyze the errors property to glean information.

Additional information:

Ideally we could even link additional information about what an Unsubscription error is.

Important note for the example above. source2 should still be torn down.

Thanks! The readable console log would be great, it would have sped up my recent debugging incident.
