To test : - Import a record with Id column (for upsert-ing) + some subfields in each composite fields. Check that only matched subfields are updated (Main issue) - Import a record with a multi-select field - Check it works + Match multi-select field on a non multi-select column, check it does not work. (Specific bug fixed in second commit is : undefined value in multi select column (corresponding to no item selected) caused error in multi-select parsing). closes https://github.com/twentyhq/core-team-issues/issues/990
