After deleting a content object from the eZ Website Toolbar, it redirects to parent content object.

If content.tree_root.location_id is the default (2) it works as expected, which means redirecting to URL alias (which looks like this: http://your-site.local/This-is-root/Do-it).
If content.tree_root.location_id is not the default, it redirects to content/view (system) URL (which look like this: http://your-site.local/content/view/full/123).

Steps to reproduce:

1. Create a new This is root folder (I'll assume its node_id is 123)
2. Edit the config file vi ezpublish/config/ezpublish.yml and change the eng siteaccess:
   Unable to find source-code formatter for language: diff. Available languages are: actionscript, ada, applescript, bash, c, c#, c++, cpp, css, erlang, go, groovy, haskell, html, java, javascript, js, json, lua, none, nyan, objc, perl, php, python, r, rainbow, ruby, scala, sh, sql, swift, visualbasic, xml, yaml

   ezpublish:
           eng:
               session:
                   name: eZSESSID
   +            content:
   +                tree_root:
   +                    location_id: 123
   

3. Create the Do it article under the folder you created.
4. Open http://your-site.local/site/This-is-root/Do-it to see the same article without the location_id setting
5. Open http://your-site.local and log into the frontend with the admin user
6. Navigate to http://your-site.local/Do-it to see the article you just created
7. Click on the trash icon on eZ Website Toolbar and delete the Do it article
8. Confirm you will be redirected to http://your-site.local/content/view/full/123 instead http://your-site.local/
