[1155612] upgrade from jon 3.1.2 to jon 3.3.0 er05 does not work
Fix an install issue when upgrading from a BSN (before storage nodes)
version.  Go back to the legacy db-upgrade step that adds the entire
rhq_storage_node table and make it match the same table definition you'd
get from a new db.  Because no SNs existed at upgrade-time the version
column updater never gets a chance to execute. And therefore the insertion
of the initial SN fails.
