Description of problem:
If an associated item is duplicated in the XML generated for a Content
Item (say as a related link and as a featured item on a home page
component), the second instance of the item has only the OID (none of
the content). In effect, this means that the element will be skipped
on the output page.

London change 38715 resolves this by recusively copying the duplicate
element, unless it is a reference to a parent of the item.

Version-Release number of selected component (if applicable):
5.2,6.0,rickshaw

How reproducible:
always

Steps to Reproduce:
1.create a content item which references another item more than once
2.preview the item
3.second instance of the item is missing detail
