Excessive GraphQL calls on server side rendering

[MrOrz]

Although we have set {ssr: false} to some query, it's still invoked in server-side rendering. This puts extra load to SSR server.

Logger added to BatchHttpLink:

fetch: (uri, options) => {
  console.log(
    'FETCH',
    options.body &&
      (JSON.parse(options.body) || []).map(
      ({ operationName }) => operationName
    )
  );
  return fetch(uri, options);
}

I seem to have a similar issue when setting up Material UI SSR + next-i18nnext SSR. The way Apollo detects SSR seems to be broken in certain scenarios when playing too much with React SSR, it might change some internal state
