fix(spec): the objectql autonumber rewrap copies only cause off the caught error, so say "and/or"

The sentence grouped it with the `driver-sql` rewraps as copying "`code` and
`cause`"; the objectql site sets `code` as a literal and copies only `cause`.
The claim that matters — none of them copies `status` — is unchanged.
