Impacted versions:
Odoo 12 Community Version

Steps to reproduce:

1. Clean install on Debian server.
2. Install Website module.
3. Activate debug mode
4. Go to Settings/Users/Form

Current behavior:
Several menu options, with group='base.group_no_one', are not displayed in debug mode.

Expected behavior:
All fields with the group 'base.group_no_one' should be displayed for users linked to that group.

Video/Screenshot link (optional):
The ratio button to define the user type is not displayed, despite the fact, that the current user has the right linked with the group='base.group_no_one'.
