While doing the proverbial other things, I noticed that the grammar
symbols publication_name_list and publication_name_item are pretty
useless. We already use name_list/name to refer to publications in most
places, so getting rid of these makes things more consistent.
These appear to have been introduced by the original logical replication
patch, so there probably wasn't that much scrutiny on this detail then.

Subject: [PATCH] Remove unnecessary grammar symbols
Instead of publication_name_list, we can use name_list. We already
refer to publications everywhere else by the 'name' or 'name_list'
symbols, so this only improves consistency.
