no issue
- we recently started wrapping rollbacks in transactions (https://github.com/TryGhost/knex-migrator/pull/161)
- in a number of migrations we were calling `model.destroy()` without passing through the options which includes the current transaction
- for models which are using `bookshelf-relations` this could result in an internal `SQLITE_BUSY: database is locked` error because it tries to run queries against tables that have been locked by previous queries in the transaction
- by passing through the options when calling `.destroy()` it allows the `bookshelf-relations` to re-use the same transction avoiding the database lock problems
