Fix bulk batch export of badges and uploads

What does this MR do and why?

Currently bulk_import exporting of badges and uploads is broken if param[:batched] is set to true while exporting https://docs.gitlab.com/ee/api/group_relations_export.html#schedule-new-export

This fixes export of those relations

This needs to be backported to at least 16.2 where batched migrations was first enabled: #421138 (comment 1595759370)
