open-tx-log and listen with-ops?/with-tx-ops? should surface as much non-evicted data as possible

[refset]

e.g. :xtdb.api/delete should be conformed with the original :xt/id if it is still available, otherwise there are very limited options for reversing the lookup of an #xtdb/id (without resorting to internal APIs), possibly just this:

  (with-open [n (xt/start-node {})]
    (xt/submit-tx n [[::xt/delete :foo]])
    (xt/submit-tx n [[::xt/put {:xt/id :foo}]])
    (xt/submit-tx n [[::xt/delete :foo]])
    (xt/sync n)
    (defn xtdb-id->xt-id [node eid]
      (with-open [i (xt/open-entity-history (xt/db node)
                                            eid
                                            :asc
                                            {:with-docs? true
                                             :with-corrections? true})]
        (:xt/id (some :xtdb.api/doc (iterator-seq i)))))
    (xtdb-id->xt-id n (xtdb.codec/new-id :foo))) ;;=> :foo
