In the case Teleport `second_factor` is set to `on`, it is possible for a user to only have OTP configured. Prior to this commit this would result in a auth fail as the created challenge only supported TOTP. Server side would recieve an incomplete `AuthenticateWebUserRequest` object, which fails validation via `CheckAndSetDefaults` and as such only a failed login audit event was emitted with no additional logs. This mode of failure can be reproduced with `tsh bench -d web sessions --auth=local`. changelog: Fixed fallback for web login when second factor is set to `on` but only OTP is configured.
