As mentioned in the comments of MBS-5450 we currently show pseudo-releases in the ReleasesWithoutCAA report, but we don't generally want pseudo-releases to have cover art (the guideline at https://musicbrainz.org/doc/Style/Specific_types_of_releases/Pseudo-Releases says it's acceptable to add cover art if no official release exists to be deleted once the official release is added, but that's very different from actually encouraging adding "missing" cover art to them). As such, we should just exclude pseudo-releases when generating this report.
