Add a few more app exclusions when dumping data for rbdemo.
Review Request #6018 — Created June 23, 2014 and submitted
The rbdemo data dump contained an evolution history of the database,
which caused some major problems when resetting the demo after upgrading
the database. We now exclude this, along with some admin apps that we
don't need to ship.
Generated a dump and loaded it without issues.
