AccountDataMigrator hardcoded the v2 accounts DDL (schema/2.json), so
copyAccountTables created a table missing the authError column PR #472
added in v3 (schema/3.json). Room then rejected the pre-packaged
accounts table as an invalid schema, failing every
AccountDataMigratorTest instrumented test on every API level.
Add `authError` TEXT to CREATE_TABLE_SQL["accounts"] to match the
exported v3 schema exactly, and repoint the DDL-guard test
(migratorDdlMatchesExportedAccountDatabaseSchema) at 3.json so it
would have caught this drift.
