InstaREPL doesn't respect :refer-clojure :exclude libraries

[cakenggt]

The InstaREPL does not correctly exclude core libraries when they are excluded in the ns tag with :refer-clojure :exclude

Steps to reproduce:

1. Execute lien new app exclude-test
2. Go into src/exclude_test/core.clj and turn InstaREPL on
3. Change the contents of the file to the following

   
   (ns exclude-test.core
   (:refer-clojure :exclude [println])
   (:gen-class))

println

(defn -main "I don't do a whole lot ... yet." [& args] (println "Hello, World!"))

4. See that the `println` line references clojure.core instead of nothing
