Github UserName 변경 시 Update가 아닌 새로운 User 삽입

	private User saveOrUpdate(OAuthAttributes attributes) {
        User user = userRepository.findByName(attributes.getName())
                .map(entity -> entity.update(attributes.getEmail(), attributes.getPicture()))
                .orElse(attributes.toEntity());

        return userRepository.save(user);
    }

userName을 기준으로 user를 찾고 update를 수행하는데 github에서 username을 변경하면 내 DB와 동기화가 되어있지 않아 새롭게 들어온 User로 판단하고 userRepository.save를 수행하게된다.

이를 해결하는 방법이 없을까 ?
