steps to reproduce

1. npm run clean && npm run start
2. visit: http://localhost:8000/__graphql
3. run the following query:

query MyQuery {
  item {
    featuredImg {
      childImageSharp {
        gatsbyImageData
      }
    }
  }
  product {
    id
    featuredImg {
      childImageSharp {
        gatsbyImageData
      }
    }
    items {
      id
      featuredImg {
        childImageSharp {
          gatsbyImageData
        }
      }
    }
  }
}

4. Notice product.items[i].featuredImage is null. This should return the same image data that is returned on item.featuredImg.
