Correct links rendering on a domain based wiki

NOTE: For this test, it's best to use a new XWiki instance.

1. Add 2 custom domains in Information/etc/hosts/ file: one to be used for Main Wiki (e.g. domain1.com) and one for the subwiki (e.g. domain2.com)
2. Before starting the XWiki instance, edit Informationxwiki.cfg, uncomment and set Informationxwiki.virtual.usepath=0
3. Start and access the instance with a custom domain previously set (e.g. domain1.com)
4. Login as Admin
5. Create a subwiki by setting the Alias as the other domain (e.g. domain2.com)
6. Create an user (e.g. U1) on Main Wiki
7. Login with U1, go to Notification Settings and set Pages Notifications toggles to ON
8. Click on a Page Notifications button and follow the entire wiki
9. Go to subwiki, click on a Page Notifications button and follow the entire wiki as well
10. Login as Admin
11. Create, update and comment a page (Sub1) on subwiki
12. Create, update and comment a page (M1) on Main Wiki
13. Go to subwiki, login as the user U1
14. On notifications list, observe the links pointing to the page from Main Wiki (e.g. M1) and the links to Admin's profile
