/*

|
* 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.
