Fix compromise detection

[nivex]

Compromise detection has inverted logic handling response_code and did not honor the settingsFilename variable.

On a relatively new Linode running Ubuntu bionic, I couldn't get Pepperminty Wiki past Error: peppermint.json.compromised exists on disk, so it's likely you need to block access to 'peppermint.json' from the internet. If you've done this already, please delete peppermint.json.compromised and reload this page. despite blocking access to peppermint.json (curl got 403). Changing the logic from OR to AND got me past the first run checks.

Hey, thanks @nivex! Great spot. I'll merge this and do a point release.

I tweaked the formatting of your code a bit too.
