An sqlite3 database may be opened with the x-no-tx-wrap=true query
parameter if the user would prefer to retain full control over the
bounds of their transactions. With x-no-tx-wrap enabled, migrations
should contain explicit BEGIN and COMMIT statements. This (optional)
behaviour for the sqlite3 driver is consistent with the default
behaviour for other drivers.
Fixes#346.
