Use RunLoop now.

Actually, why do you need a messageloop for this test?

I don't, removed! (artifact of copy-pasting)

Check the type.

[tguilbert, 2016/06/24 21:18:42]

Done.

We can specify in the API that if the type is URL, then GetStream() should not
be called. Then we don't need to test this.

Done.
