Expected behavior

Invoking clojure-add-arity in a single-arity function with metadata on the arglist should result in a function that still has that arglist meta.

For example, if I have

(defn string ^String [x] (str x))

After clojure-add-arity, I should have

(defn string ([]) (^String [x] (str x)))

Actual behavior

New airty is added between metadata and the existing arglist, consequently moving the metadata off the original arglist. The metadata is no longer meaningful.

(defn string ^String ([]) ([x] (str x)))

Steps to reproduce the problem

Invoke clojure-add-arity at any point in a single-arity function with metadata on the arglist.
