I've included a sample project with a MigrationTest class that fails like so when invoking MigrationTestHelper:

java.lang.IllegalStateException: Migration didn't properly handle: user_fts
Expected: FtsTableInfo{name='user_fts', columns=[name, rowid], options=[]}
Found: FtsTableInfo{name='user_fts', columns=[name], options=[]}

Yet the AppDatabase_Impl sees the schema as being correct.

The root cause seems to be that they treat the implicit `rowid` column differently: the generated schema json file includes the `rowid` field causing MigrationTestHelper to expect its presence, but AppDatabase_Impl's onValidateSchema method doesn't check for rowid.

I believe AppDatabase_Impl has the correct behaviour in this case: MigrationTestHelper uses FtsTableInfo which uses `PRAGMA table_info()` to discover the columns of the fts table, which *doesn't* return `rowid` as being one of the columns, but MigrationTestHelper is comparing that FtsTableInfo with the json data which *does* include `rowid`, so it thinks the schema doesn't match.
