jvoisin cc35e5b0e5 test: cover children traversals with duplicate source nodes 
A Selection's Nodes field is exported, so callers can build a selection that
holds the same node more than once. Add a regression test asserting that
Children, ChildrenFiltered and Contents deduplicate the shared child set
rather than returning it once per duplicate source node.
