Using idents as query parameters doesn't unify then

[purrgrammer]

While using idents I noticed that keyword literals are unified just fine in queries. However, when passing ident keywords as arguments they are not unified. A minimal example looks like this:

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

(def uri "datahike:mem:memdb")

(def schema [{:db/ident :ident
              :db/valueType :db.type/ref
              :db/cardinality :db.cardinality/one}
             {:db/ident :an/ident}])

(d/create-database uri :initial-tx schema)

(def conn (d/connect uri))

@(d/transact! conn [[:db/add 1 :ident :an/ident]])
@(d/transact! conn [[:db/add 2 :ident :an/ident]])

(d/q '[:find ?e
       :where [?e :ident :an/ident]]
     (d/db conn))
;;=> #{[2] [1]}

(d/q '[:find ?e
       :in $ ?ident
       :where [?e :ident ?ident]]
     (d/db conn)
     :an/ident)
;;=> #{}

The above queries are equivalent, so I'd expect to get the same result from both.

Thanks. It shouldn't behave like that. I'll add a test and fix in the next patch release.
