Move the duplicate page/resource filter

Move the removal of duplicate content and resource files after we have determined if we're inside a leaf bundle or not.

Note that these would eventually have been filtered out as duplicates when  inserting them into the document store, but doing it here will preserve a consistent ordering.

Fixes #12013
