Unable to edit a 'direct' room setting in the admin due to the name

[Jeanstaquet]

Description:

When you are in the admin and want to change a room 'd' setting, it doesn't work because it takes into account the name that is set automatically and therefore tries to save that name. Since the name is not valid and should not be registered, we cannot change the setting.

Steps to reproduce:

1. Go to admin
2. Go to rooms
3. Try to edit a direct room setting
