🐛 No fallback when no name

[AntoLC]

Bug Report

Users depend the informations register in their IDP can not have a name.
If it happen, we can have a case where we don't have any information about the owners or admins.

To reproduce

• Create a user without name but email
• Create a doc
• Invite this person as a admin or owner
• Invite another person as a reader
• Connect with this reader person
• Open the doc
• Open the modal
• The bug is here

Possible solution

Have a fallback on full_name if it is empty :

docs/src/backend/core/api/serializers.py

Lines 32 to 38 in c534fed

	class UserLightSerializer(UserSerializer):
	"""Serialize users with limited fields."""
	class Meta:
	model = models.User
	fields = ["full_name", "short_name"]
	read_only_fields = ["full_name", "short_name"]

Ex (transform all punctuation in dash as a light obfuscation ?):

• user_3@test.com become user-3
• john.doe@test.com become john-doe3
