Hook and rule get the new email address twice and not the old email address

Hook and rule get the new email address twice and not the old email address. I've made a small change in the `email_confirm_user_change_mail` function right before the user_save call (around lines 254 - 258):

$old_mail = $account->mail;
user_save($account, array('mail' => $new_mail, 'login' => REQUEST_TIME, 'email_confirmed' => TRUE));
module_invoke_all('email_confirm', 'email confirmation', $account->uid, $old_mail, $new_mail);
if (module_exists('rules')) {
  rules_invoke_event('email_confirm_email_change_confirmation', $account, $old_mail, $new_mail);
}
