Close DB in junits

Modified some of the junits to close the DB.
In addition, one of the junits was apparently dependent on a previous
test method adding records to the DB, thus the test methods were
actually order dependent, even though no annotations were used to
enforce the order.  Modified that method to insert the data, itself, so
the test methods are no longer order dependent.
