Publishing multi-module projects via hangar-publish fails

[NonSwag]

Observed/problematic behavior

When publishing a multi-module project via hangar-publish, the server returns an error code 400 saying Error uploading version, returned 400: version.new.error.duplicateNameAndPlatform even though there are clearly no duplicate platforms defined

Expected behavior

Server should accept publication

Steps to reproduce

1. Create a multi-module project with at least 2 publications
2. execute task publishAllPublicationsToHangar
