[JENKINS-16332] More logging at FINE in hudson.model.User.
Running hypothesis: something historically saved a user configuration file with a bogus fullName;
thereafter anyone calling User.get(correctFullName) will get a User with the old fullName.
This would make the bug unreproducible in fresh Jenkins installations.
