- TMDO_Zone_Router::delete_post() deleted from wp_wpdo_hot_/cold_{post_type}
whenever fields were registered for that zone, so every post delete on a
HivePress site (cold fields registered, module idle, table never created)
logged a "table doesn't exist" error. Hot and cold deletes now also need
the table to exist; module state is not checked, so a table left by a
rolled-back module still loses the rows of deleted posts.
- Live suite zero_side_effect: saving / updating / deleting an hp_listing
issues no query on missing zone tables (covers PR-054 and this PR).

serialized 9/9 PASS (old code: zero_side_effect FAIL); unit 687 OK,
