Delay DB updates until all policies processed

If an exception is thrown in the middle of processing policies, it's
possible for the DB to reflect a partial deployment.  This change
queues the DB changes so that they're all made at once, after all
policies have been processed.
Extracted sort() into a common place.
Corrected some comments.
Simplified the list retrieval in the junits since all DB creates and
updates are now batched together into one operation each.
