feat: Change default path computing algorithm - MEED-8176 - Meeds-io/…

…MIPs#173

Prior to this change, when the user attempts to access anonymously to the portal using root website url (/), the request is forwarded to the first anonymously accessible site which isn't marked as 'non default site' (like spaces public sites). This change will adopt this new strategy:
- When the user accesses to the Website and the public site is anonymously accessible, the forward request to the public site
- When the user accesses to the Website and the public site isn't anonymously accessible, the forward request to the login page (even if other sites are publically accessible)
- When the user is authenticated and has a favorite path, then forward the request to the user favorite home path
- When the user is authenticated and doesn't have a favorite path, then forward the user to the first accessible path switch display order as established in Sidebar Menu which changes the display Order automatically.
