This PR has two parts: * Add locking to goth and gothic calls with a RWMutex The goth and gothic calls are currently unlocked and thus are a cause of multiple potential races * Reattempt OAuth2 registration on login if registration failed If OAuth2 registration fails at startup we currently disable the login_source however an alternative approach could be to reattempt registration on login attempt. Fix #16096 Signed-off-by: Andrew Thornton <art27@cantab.net>
