gatsby-plugin-sitemap: restore the ability to pass additional query data

[abohannon]

Summary

It appears that with the latest version, the ability to pass additional data in the sitemap query was removed. Our sitemap is constructed using data from site, allSitePage and another query, but after updating our additional query data is no longer being returned. The issue seems to be with the explicit shape being returned on line 55 in internals vs. returning r.data as before.

Basic example

The query we're using that no longer works is:

const sitemapPageQuery = `
{
  site {
    siteMetadata {
      siteUrl
    }
  }
  allSitePage {
    nodes {
      path
      context {
        index
        filterValue
      }
    }
  }
  allContentfulP0001Page {
    nodes {
      robotsMetaTags
      url
    }
  }
}
`

allContentfulP0001Page data comes back undefined.

Motivation

Being able to pass additional query data allows us to tailor the creation of our sitemap. It would be helpful if this feature could be restored.

@moonmeister Any thoughts on this?

[abohannon]

We were able to refactor to include the data we needed on the allSitePage query and get rid of the additional individual page query, but I still think it's helpful to be able to make a broader query here, in case additional data is needed.

hmmm...sounds like we found some code that wasn't covered by tests. I think I may know where I caused this...I should have some time in the next couple days to take a look. Anyone else is welcome to if I don't get to it.
