When a new parent is added to a tree template like types, taxes or tax codes, the corresponding record of the new template parent is not yet created. So we need to use a default value for the parent and update again the tree after creating the new records. Closes #12755 (grafted from 561f9c7dbdc2a2c39c1fe5f6bf7274d01ee9ebd6) --HG-- branch : 7.0
