hash changes for the same transaction

[kordano]

The same transaction on a db value results in different hash values:

(:require '[datahike.core :as d])

(def db (d/db-with (d/empty-db) [{:db/id 1 :name "Konrad"}]))
(hash (d/db-with db [[:db.fn/retractEntity 1]]))
;; => 32706373
(hash (d/db-with db [[:db.fn/retractEntity 1]]))
;; => 13589158

The hitchhiker-tree has mutable helper objects attached to tree nodes, maybe its hashes break equality. One way to fix this would be to implement hashing on tree nodes explicitly.
