Follow #30454 And fix #24957 When using "preferred_username", if no such field, `extractUserNameFromOAuth2` (old `getUserName`) shouldn't return an error. All other USERNAME options do not return such error. And fine tune some logic and error messages, make code more stable and more friendly to end users.
