Restore the debug log helper of the auth component

Browse source 
701e85a removed M365_Login_Auth::log() while it is still called on every
failure path of the callback (token exchange, token verification,
object ID mismatch, group checks). Those sign-ins ended in a PHP fatal
error instead of the error message on the login page.
