gatsby-demo: error when toggling draft on and off again

[DirtyF]

Description

Given I am editing a blog post on gatsby demo
When I toggle the draft off and on again
Then the following error is displayed 👇 

Error: useRemarkForm(markdownRemark) 'markdownRemark' was not found on the top node of the graphql query

1. Check if the 'markdownRemark' attribute is included in the GraphQL query. For example:

export const pageQuery = graphql`
  query BlogPostBySlug($slug: String!) {
    markdownRemark(fields: { slug: { eq: $slug } }) {
      ...TinaRemark
      // etc...
    }
 }

2. If you are using an alias, For example:

   export const pageQuery = graphql`
     query BlogPostBySlug($slug: String!) {
       markdownRemark: markdownRemark(fields: { slug: { eq: $slug } }) {
          ...TinaRemark
       // etc...
       }
    }

  then you can optionally use the 'queryName' option to specify a new property in place of 'markdownRemark':

    export const remarkForm(BlogPostTemplate, { queryName: markdownRemark })
`

Expected result

No error when toggling draft status.

I can't reproduce this. I think this has been fixed by that change I made a bit ago.
