title: eZ Platform site access for translations not working as expected
body: <p>I am having no joy in successfully getting a translated site-access to work. I have a clean install of the latest stable ezplatform, i have only the default content types "folder" and "article". I have one content object after the root location and have the said object in english and german (where the new language code is <code>ger-DE</code>. This is my attempt at an ultra basic ezplatform.yml:</p>
  
  <pre><code>siteaccess:
      list:
          - site
          - de
          - en
      groups:
          site_group:
              - site
              - de
              - en
      default_siteaccess: de
      match:
          URIElement: 1
  
  # System settings, grouped by siteaccess and/or siteaccess group

                  root_folder:
                      template: "full/home_page.html.twig"
                      match:
                          Identifier\ContentType: "home_page"
  </code></pre>
  
  <p>I fire up the server locally with the server start command, I can access the sample object with the following url: <a href="http://localhost:8000/sdc" rel="nofollow noreferrer">http://localhost:8000/sdc</a>
  I can access the new site access via <a href="http://localhost:8000/de_site" rel="nofollow noreferrer">http://localhost:8000/de_site</a>  and it looks like it hits the site access as no 404 is thrown
  But.. whatever I do it always redirects to <a href="http://localhost:8000/de_site/login" rel="nofollow noreferrer">http://localhost:8000/de_site/login</a> instead of hitting the actual content tree and content override for type ‘article’</p>
  
  <p>Is there a glaring mistake in my yml config attempt or is there something I have to also do to make this work?</p>
