adds some sanity checks before the actual scan

The change with the quotes where done by my linter but I would still suggest to apply them because fixed strings should always use ' while " should only be used if you actually want to substitute a variable into the string.

As you can see on the Strings page of the PHP Docs with the double quotes many interpretations are done that can basically be avoided doing by mistake when using single quotes.

I just realized that this pr is only logging and not avoiding the actual problem. We would have to either return an unknown verdict or so that and tag the ID as won't scan.

But won't scan might not be correct when you read the customer issue. There is a chance that we tag the wrong file (which might be a general issue in our App). And just returning unknown might lead to the same file being scanned over and over again.

I suspect there is still something wrong with our query, so we get out wrong Ids from it or we miss some kind of enabled status in the db. Just speculations thought.
