Returning future on HipsterCollection.fetch

Ah, you're right, of course. The fetch() method would be silly without returning a future. But again, this need to run through HipsterSync, which does return a future.

I believe that, if you switch to something after_call = HipsterSync.call('read', this);, then you ought to be able to achieve the same results. That is after_call.then .... and then return after_call. If you have time, please give it a try. Otherwise I'll add it in there in a bit.

Thanks again for the PRs. Sorry about the ridiculous delay.
