CHD Re-scan after --input-checksum-quick finds no files in archive #1942

Describe the bug
I've been experimenting with scanning/filtering CHDs. I'm doing this so that I can store my collection in a compressed way, but still be able to play games without decompressing and taking up lots of extra space. For CHDs that were manually created from bin/cue using chdman createcd -i <cue_file> -o <chd_file>, when scanning with the option --input-checksum-quick, it fails with the error didn't find any files in the archive, because no checksums in the CHD headers match the supplied DAT. That is annoying, but not the bug. The bug is that when I then re-scan WITHOUT the --input-checksum-quick option, the file is being read from the cache, igir sees that no matching files were found originally, and skips the CHD entirely with the same error as before, didn't find any files in the archive.
Expected behavior
I would expect that if a scan does not show any files when scanning with --input-checksum-quick, then nothing would be added to the cache. This way, when re-scanning without that option, full decompression happens. Or, add a flag in the cache that nothing was found last scan with --input-checksum-quick, and it should be re-scanned next time.
