Fix hostCheats check not disabling (#3691)

## Description:

Currently if you deselect Host cheats, any active host cheats will still
be active. This fixes it so if you deselect Host cheats, all the cheats
are disabled.

## Please complete the following:

- [X] I have added screenshots for all UI updates
- [X] I process any text displayed to the user through translateText()
and I've added it to the en.json file
- [X] I have added relevant tests to the test directory
- [X] I confirm I have thoroughly tested these changes and take full
responsibility for any bugs introduced

## Please put your Discord username so you can be contacted if a bug or
regression is found:
