Overview

When a project is deleted, database-level ‘ON DELETE CASCADE` then removes all records in the hierarchy down to and including Projects::ImportExport::RelationExportUpload. There is no FK relation between RelationExportUpload and Upload records, so those must be cleaned up at the code level. We can leave the other records (Projects::ImportExport::RelationExport, etc.) intact, as they will be removed by the FK cascade.
