[FIX] website_portal: redirect to login for '/my' controller

Current issue without this patch:
On a bare database, install `website_portal` and go to `/my/home` logged out.
You get to an empty page where you can see Public User's details.

Expected behavior with this patch:
User should be redirected to the login page.

Additional notes:
- Other submodules (`website_portal_sale` and `website_project_issue`) were
  actually implementing this, so that is removed BTW and relies in base
  module's now sensible behavior.

This commit closes #12775
