Describe the bug

When using isFragmentReady function with a fragment that has a deferred nested fragment, the function returns only true, this is related to the fact that __meta__.deferredFields is not populated on fragments, but only on queries.

e.g.

//@ts-ignore
const Fragment = gql(/* GraphQL */ `
  fragment Foo on Foo {
    value
  }
`);


//@ts-ignore
const NestedFragmentWithFragment = gql(/* GraphQL */ `
  fragment fooNested on Foo {
    id
    ...foo @defer
  }
`);
