Migration with attachments removes attachment mime types

Issue

I'm trying to migrate a collection which contains attachments. Even though I don't change _attachments at all, the content_type is lost after the migration (which causes different errors). The migration itself is successful.

It looks like the data migrator calls bulkAddRevisions here with documents which look like this:

{
    ....,
    _attachments: {
        foo: {
            data: Blob,
            type: 'text/plain'
        }
    }
}

This looks more like RxDocumentWriteData than RxDocumentData (which bulkAddRevisions is supposed to take as an argument). If I replace pouchSwapPrimaryToId with rxDocumentDataToPouchDocumentData in bulkAddRevisions everything seems to work.
