Reproduction steps:

1. Set up and start a portal
2. Create a display page template mapped to the basic web content structure.
3. Place the 'display page content' component on the display page template, and publish the template.
4. Mark this as the default display page template.
5. Create a basic web content article.
6. Edit the web content article and find the friendly url of the article and navigate to that URL
7. View the sitemap.xml ( http://localhost:8080/sitemap.xml )

Expected behavior: the link to the web content's friendly URL should show up in one of the referenced sitemap.xml links
Actual behavior: web content's friendly URL does not appear anywhere in the sitemap.xmls

Notes:
This works correctly when a widget page is used as specific display page of the web content (widget page with a default Asset Publisher on it). In this case the display page's sitemap.xml shows all the web contents that are assigned to it, based on JournalArticle.layoutUUID field. In the code, it queries the web contents here: JournalArticleSitemapURLProvider.visitLayout(..)
