Users.app in 0.7.0 no longer works after upgrades

After upgrades (for security etc.), the _Users_ application is no longer usable.

```text
mowa219-gjp4-hello-070% /Applications/Preferences/Users.app/Users
The Python module 'translate' is not available. The application will run untranslated.
Could not find suitable .ts files in /Applications/i18n
Traceback (most recent call last):
File "/Applications/Preferences/Users.app/Resources/adduser.py", line 191, in
widget = Users()
File "/Applications/Preferences/Users.app/Resources/adduser.py", line 41, in __init__
self.load_ui()
File "/Applications/Preferences/Users.app/Resources/adduser.py", line 52, in load_ui
for e in self.findChildren(QObject, None, Qt.FindChildrenRecursively):
NameError: name 'QObject' is not defined
```

**To Reproduce**

2. upgrade from end-of-life FreeBSD 13.0-RELEASE, to 13.1-RELEASE-p2
3. `pkg delete localize` to avoid `https://github.com/helloSystem/ISO/issues/404`
4. unlock all packages except `hello`
5. upgrade packages
6. Preferences
7. Users

**Expected**

8. the application.
