Logout redirecting to URL("/") does not redirect to login page when root_path is set to non-default

[ktanff]

Describe the bug

After logging out, app redirects to root "/" of the host, which makes an undesired experience, when the app is deployed under a path else than the default root_path, that is a common case for one who puts gradio behind a reverse proxy.
