Failed logins are not logged

[aspark21]

Would expect failed logins to be recorded as \core\event\user_login_failed and/or in apache logs but these are nowhere to be found even on highest debug settings.

In particular with the $this->log calls would have expected the reason for the login failure to be exposed into the event
