When defining var twice but from other file, metadata isn't changed

[borkdude]

Repro:

user=> (require '[sci.core :as sci])
nil
user=> (sci/binding [sci/file "duuude"])
nil
user=> (def ctx (sci/init {}))
#'user/ctx
user=> (sci/binding [sci/file "duuude"] (sci/eval-string* ctx "(ns dude) (defn foo [])"))

{:name foo, :ns #object[sci.lang.Namespace 0x1c80f8dd "dude"], :file "duuude", :arglists ([]), :line 1, :column 11}

;; in JVM Clojure:
user=> (alter-var-root #'*file* (constantly "duuude1"))
"duuude1"
user=> (defn foobar [])
#'user/foobar
user=> (:file (meta #'foobar))
"duuude1"
user=> (alter-var-root #'*file* (constantly "duuude2"))
"duuude2"
user=> (defn foobar [])
#'user/foobar
user=> (:file (meta #'foobar))
"duuude2"
