Archivematica can't download transfers if the storage manifest is too big

I thought I'd fixed this:

Traceback (most recent call last):

    response = callback(request, *args, **kwargs)

We should probably fix this, but if we deploy the bag browser as the way to download bags it becomes much less important.

Parking until we do the workflow stuff. Required for https://github.com/wellcomecollection/platform/issues/4184

Fix deployed.
