Prevent a React dev warning when a loading Query component is unmounted

[jaydenseric]

If you unmount a Query component (specifically the GraphQLQuery component within it) while it is still loading a query, you see a React dev warning like this:

This is because a setState call happens after the request is complete to update the loading state as false, see here. This should be prevented from happening after the component has unmounted.

I'm doing a thing where I use the Redirect component from @reach/router and see this a lot.

Yep, it's annoying but at least harmless. I hope to be able to get to it this weekend; I've recently been busy soft-launching https://enamor.app (which BTW happens to use graphql-react ✌️).

🚢 Fixed in v3.
