Add support for React 16.3 getDerivedStateFromProps

[wmonk]

When using getDerivedStateFromProps the lifecycle methods of react-refetch are not called.

I suppose react-refetch should be updated to use the appropriate methods.

Possibly also need to update hoist-non-react-statics

Yea I noticed when I tried 16.3 that none of the my PromiseStates were included in the props at all :S
