fix: Mapping completion criteria

[LautaroPetaccio]

This PR changes the mapping completion criteria:

• Collections that contain items that are not published and have migrations that are not set will be marked as incomplete.
• Items will be marked as having an incomplete mapping if they have a curation (they were published) and it's flagged as not having its mappings as complete or if they don't have mappings set.
