* Let the "stored hash uses not supported mechanism" bubble up.
  Instead of just a "login failed", an error is raised hinting
  that something is broken.
* Improve exception message #1533818591: If an upgrade or new
  installation has been performed on a system that does support
  argon2i, users are upgraded to this mechanism. If the instance
  is later deployed to a server that does not support argon2i, the
  hash comparison will fail.
* Improve exception message #1533822084: This one is usually only
  raised if a core upgrade from v8 to v9 has just been performed on
  an instance that does not support argon2i, and a backend login is
  executed before the install tool silent configuration upgrader
  configured the system properly.
