Improve `preview` output table

[depombo]

[aguillenv]

I've been taking a look at this task. I think it is not a bug but something to maybe improve. My confusion came from:

• The description column showing the cloud ids does not make too much sense to me. Maybe we can rename it to cloud_id?
• When there's no cloudIdavailable in the database, the MapperInterface is defaulting to a primary column in DB, so in some cases is showing duplicated ids when it is not necessary.
• We might need to review that we are showing both ids on update/replace, if preview_apply just show DB id on creating, if delete, just show cloudId and not DB id (because it is not anymore in the DB). Follow respective logic with sync cases.
