 * This test uses a formhistory.sqlite with schema version set to 999 (a
 * future version). This exercies the code that allows using a future schema
 * version as long as the expected columns are present.
 *
 * Part A tests this when the columns do match, so the DB is used.
 * Part B tests this when the columns do *not* match, so the DB is reset.
