Ticket 48813 - password history is not updated when an admin resets the password
    
    Bug Description:  When an admin resets a password the current password is not
                      stored in the password history. This incorrectly allows the
                      user to reuse the previous password after the reset.
    
    Fix Description:  When a password is being reset by an "admin", still grab the
                      old password so we can correctly update the password history.
