A field that resolves to undefined is not present in response

[alexstrat]

If a resolver resolves undefined, the corresponding field is not present in the results' data, whereas according to specs the corresponding field should be null:

If result is null (or another internal value similar to null such as undefined or NaN), return null.

const resolvers = {
  Query : {
    foo: () => of(undefined),
    bar: () => of('bar')
  }
};
const res = await graphql(gql`{foo, bar}`, schema).toPromise();
// actual: res = { data : { bar: 'bar'}};
// expect: res = { data : { bar: 'bar', foo: null}};

Made me run into compatibility issues such as apollographql/apollo-client#4267
