Remove incorrect SetIndirect call - indirect already set via WithIndirect

The CTE indirect is already retrieved at line 663 and set on
ExtendedTableMetadata via WithIndirect(indirect) at line 720.
The SetIndirect call was incorrect as HeirarchyObjects.SetIndirect()
expects RelationDTO, not astindirect.Indirect.
