  * 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.
