About a `sudo` on ir.ui.menu, this commit (3649b7f359) removed it,
this commit (3d0cc2d6d2) re-added it.
Since portal user can not go on /web anymore, I think portal does not need to read ir.ui.menu.
Here some news scenario:
- if website is not installed, portal can log in, but will be redirected to login page
with an error message 'only employee can access'. Indeed, there is no page to display for
such user.
- if website is installed, but not website_portal, portal user can log in and will be
redirected to homepage. If he tries to manually access to /web, he will be redirect to
login page with access error (even if he will still be logged).
- if website_portal is installed, the portal user can fully enjoy its features.
