[BUGFIX] Set parent uid in newly created IRRE child record

When creating a new IRRE child element the uid of the parent element
was not set. This is a problem when you use an itemsProcFunc for a
select column which relies on the parent's element uid to show
according values. With the parent uid you can query the stored values.
