Title: Revision history previews problem

Originally reported by @nicolaasmatthijs in https://github.com/oaeproject/3akai-ux/issues/2927.

> When viewing the revision history of a PDF, the preview images for the different revisions don't show.

This is because the PDF processor doesn't submit a medium image. I'll add the small/medium/large image for the first page.
