Fix handling of temp and unlogged tables in FOR ALL TABLES publications
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.
