wrap-multipart-params only includes the last value in the vector

[ibdknox]

As of Ring 0.3.11, parameters with the same name are no longer being vectorized correctly. The following code will contain only the last value:

(defn nested-test [_]
  (html
     [:head [:title "test"]]
     [:body
        [:form {:action "/submit" :method "POST"}
        [:input {:type :text :name "mything[]" :value "10"}]
        [:input {:type :text :name "mything[]" :value "20"}]
        [:input {:type :submit}]]]))

(defn submit [request]
   (println (request :params)))

Expected:
{:mything ["10" "20"]}

Actual:
{:mything ["20"]}

This is actually a problem with wrap-multipart-params, not wrap-nested-params.

The multipart middleware is not storing parameter values with the same key as a vector.

Ah whoops, updated the issue to reflect that.
