useQuery with onCompleted: infinite loop.

[vendramini]

Hello!

I had this code before updating to v3:

const {
        data: dataEvents,
        loading: loadingEvents,
        error: errorEvents,
    } = useQuery(
        getEventsQuery,
        {
            fetchPolicy: "network-only",
            onCompleted() {
                //do stuffs
            }
        }
    );

And it works without problem. After updating to v3, even an empty onCompleted callback produces an infinite loop in my component, requesting the query forever. If I take the onCompleted off, everything works well.

I found a related issue: https://github.com/apollographql/react-apollo/issues/3353#issuecomment-521130366 but the fix didn't work for me.

Thanks :)
