fix: nested list cassette scrubbers

[Justintime50]

Description

Either something changed with the cassettes saving or was never identified, but nested list scrubbers for a very specific niche set of responses weren't working due to a bad if statement. This fixes the problem and properly scrubs those.

Testing

I re-recorded the two offending cassettes.

Also re-ran the entire test suite with cassettes to ensure this shouldn't break anything else and it worked, will not commit those all though to save on git history.
