ModelInstanceDocument doc.replace, there are some fields that are not updated in db table

[lyd0]

Describe the bug

    const doc = await ModelInstanceDocument.create(ceramic, CONTENT0, midMetadata)
    await doc.replace(CONTENT1)

but in postgress ,the db table only updates 2 fields(last_anchored_at&updated_at) when doc updated, CONTENT1 data is not updated to table,maybe other fields should be updated as well
