Description

• It fixes !39815
• Here is a brief description of what this PR does
  When a user has been assigned rights by the rules, if they no longer match the rules, these rights are withdrawn and the default right is not restored. They are therefore left without authorization.

This needs a test case

LGTM (waiting for tests results). You still have to revert composer.json changes

Is there a chance some users might expect the original behavior as a way to disable a user?

It seems more logical to me to restore the default permissions to a user who no longer has specific rights. To disable them, you would simply switch the user to Active: No.
