$httpProvider request interceptor doesn't work properly with a new config

You can see the problem here: http://plnkr.co/edit/j8qiyVJAK4fwhlbWSgSm?p=preview

Basically you can clone the current config and change transformRequest and transformResponse. The new request transform function is called but the response one isn't for some reason.

The queue of interceptors that actually gets run is set up before the interceptors are ever run. So I'm not sure how that would work. Would have to be a big architectural change to facilitate that.

I think that this is fixable without too much pain.

The issue is that transformers use config object that comes from the $http closure and ignore the possibly new config object that is passed through the interceptor chain.

It shouldn't be too hard to fix this but some caution is required since this code is not trivial.

Long term we are likely going to merge the concept of transformers and interceptors into a single thing. I believe that we've done this already in AngularDart.

PRs welcome!

@IgorMinar thanks, yes it definitely makes sense to have a singular concept for these two things. For now I've hacked together a workaround in my project but if I can find a spare moment I'll try to send a PR.
