Fixes #15959 Introduced in #6540, OAUTH_REDIRECT_AT_SIGN_IN allowed skipping the log-in form to instead redirect to the external OmniAuth login provider. However, it did not prevent the log-in form on /about introduced by #10232 from appearing, and completely broke with the introduction of #15228. As I restoring that previous log-in flow without introducing a security vulnerability may require extensive care and knowledge of how OmniAuth works, this commit removes support for OAUTH_REDIRECT_AT_SIGN_IN instead for the time being.
