Recent change to liboverride data model (6a86dd5f34) forgot to add the
new 'RNA item ID pointers references' to the expander code (readfile
area).
Note that this was essentially harmless, as these IDs are expected to be
referenced by actual data (or liboverride reference pointer) as well,
they should never be the only ones pointing at a linked ID. But better
to do it properly nonetheless.
