* Remove refreshes from reconcile functions

I think there is no need for these refreshes, this change is aimed at
addressing weaveworks#450

If we have sent async reconciles to the resource, and all visible
resources are in the informer's subscriptions, then I think we don't
need to call refresh, we'll just get a call when it's needed.
