[IMP] crm (sales_team), hr_recruitment, project: fixed display of alias on kanban view. The alias is not shown when not having alias_name (left part) or alias_domain (right part) defined. Indeed only using alias_id.value is not correct, as we could have '<alias_name>' or 'Inactive Alias', depending on the missing part.
