Title: Do not include empty repeated fields in the content metadata.

When decoding into a riak_object on the server-side, this resulted in pairs like `{<<"X-Riak-Meta">>, []}`. When encoded into the JSON form for use in JS MapReduce, the expected JSON object for that meta was actually an empty list. This helps resolve the issue for both client and server.
