title: Directus - Unable to query related (One to Many) collection
body: <p>Related collections are not returned in GraphQL requests for one-to-many relationship. </p>
  
  <p>I have 2 collections <code>blog</code> and <code>comment</code> with the following relationship</p>
  
  <pre><code>blog     1 --&gt; M  comment
  comment  M --&gt; 1  blog
  </code></pre>
  
  <p>The mapping was created using a field <code>blog_id</code> in the comment collection. When I query a blog and try to fetch the related comments, I get an error:</p>
  
  <p>Query:</p>
  
  <pre><code>{
      blog {
          data {
              title
              comment {
                  content
              }
          }
      }
  }
  </code></pre>
  
  <p>Error:</p>
  
  <pre><code>"message": "Cannot query field \"content\" on type \"BlogItem\". Did you mean \"comment\"?",
  "extensions": {
     "category": "graphql"
  }
  </code></pre>
  
  <p>The reverse works. I mean when I query comments and the related blog, it works perfectly. Any idea why?</p>
