ISIS-268: Fixed tests to run with-out errors.
 - Added @FixMethodOrder(MethodSorters.NAME_ASCENDING) annotation to force tests to run in alphabetical order
 - Tests need to run in a specific order to test full life-cycle of nothing, create, test - with the database being closed and re-opened between tests.
 - added @BeforeClass on deleteHsqlDbFiles to remove hsqldb files before test suite (clears all residual database files)
