(PDB-822) Change acceptance tests to incorporate structured facts.

This patch augments our basic_fact_retrieval and import_export acceptance tests
to include structured facts, and also bumps the version of the nodes query in
the facts/find indirector so structured facts are returned when puppet facts
find is issued to the PDB terminus.
