/*
 * Applies some transformations to existing and new relations in order to display them correctly
 * relations: raw relations data coming from useRelations
 * shouldAddLink: comes from generateRelationQueryInfos, if true we display a link to the relation (TO FIX: explanation)
 * mainFieldName: name of the main field inside the relation (e.g. text field), if no displayable main field exists (e.g. date field) we use the id of the entry
 * targetModel: the model on which the relation is based on, used to create an URL link
