To Reproduce

1. On client: CodeChecker cmd login --url https://codecheckerserver.foo/ myuser
2. On client: CodeChecker cmd login -d --url https://codecheckerserver.foo/ myuser
3. On server: note that the "logged in" logs on the server include the username, but the "logged out" logs do not. It looks like this:

[INFO 2025-03-27 21:01] - 'myuser' logged in.
[INFO 2025-03-27 21:02] - '' logged out.

Expected behaviour

[INFO 2025-03-27 21:01] - 'myuser' logged in.
[INFO 2025-03-27 21:02] - 'myuser' logged out.
