If a FOR ALL TABLES publication exists, temporary and unlogged tables
are ignored for publishing changes.  But CheckCmdReplicaIdentity()
would still check in that case that such a table has a replica
identity set before accepting updates.  To fix, have
GetRelationPublicationActions() return that such a table publishes no
actions.
