Repo to demonstrate gatsby plugin error

Steps to reproduce the error

This repo is created for an issue here

1. Run npm uninstall prismjs
2. Run gatsby develop
3. Browse to localhost:{port}/___graphql and enter the following query

query MyQuery {
  allMarkdownRemark {
    edges {
      node {
        html
      }
    }
  }
}

It should give the following error

"message": "Cannot query field \"html\" on type \"MarkdownRemark\"."

If you install prismjs again, then that bug will be gone.

In my opinion, if prismjs is not installed, gatsby-remark-prismjs should throw an error to avoid this dependency confusion.
