Setting a primary key for new users is failing - weblate.auth.models.User.DoesNotExist

[JanMalte]

Describe the issue

If you are using an authentication backend which is populating a value for the primary key weblate.auth.models.User.pk for new users, the check for creating the AuditLog is failing.

I already tried

• I've read and searched the documentation.
• I've searched for similar filed issues in this repository.

Steps to reproduce the behavior

This can be reproduced in a simple django python shell (python src/manage.py shell):

from django.contrib.auth import get_user_model
User = get_user_model()
User.objects.create(pk=42, username='test')

Expected behavior

A new user is created and the id - primary key is set to 42

This is never going to be supported. Weblate creates users internally as well (for bots or token access) and these will collide with externally managed primary key.
