model/UserHandler.php: fix verifying old password in change_pw()

- if you want to verify the old password, you should compare it against 
  the OLD and not the NEW password ;-)
- fix database calls

In other words: changing the password in users/password.php works again ;-)

users/password.php:
- switch from obsolete change_pass() to change_pw()
