Fix SQL injection in logical replication origin checks.

ALTER SUBSCRIPTION ... REFRESH PUBLICATION interpolates schema and
relation names into SQL without quoting them.  A crafted subscriber
relation name can inject arbitrary SQL on the publisher.  Test such a
name.  Back-patch to v16, where commit
875693019053b8897ec3983e292acbb439b088c3 first appeared.
