[0.17.2] Other settings always asks to save changes, even when nothing changed

[braiam]

To reproduce:

- Download and unpack linux build
- Copy older saves and configuration to new installation directory
- Go to Settings > Other
- Click back or press ESC without changing anything

What happens:

Factorio asks you if you want to discard changes

What should happen instead:

If nothing was changed, no confirmation prompt should appear

Other comments:

This may be related to the off by one slider in the autosave configuration
