user_list does not work

[wush978]

Dear @sckott ,

The user_list does not work properly with default value:

> a <- user_list()
 Hide Traceback

 Rerun with Debug
 Error: length(names(body)) > 0 is not TRUE 
8 stop(sprintf(ngettext(length(r), "%s is not TRUE", "%s are not all TRUE"), 
    ch), call. = FALSE, domain = NA) 
7 stopifnot(length(names(body)) > 0) 
6 body_config(body, encode) 
5 perform(handle, writer, method, opts, body) 
4 make_request("post", hu$handle, hu$url, config, body_config(body, 
    encode)) 
3 POST(file.path(url, ck(), method), body = body, ...) at zzz.R#23
2 ckan_POST(url, "user_list", body = body, ...) at user_list.R#14
1 user_list() 

I guess the reason is that both q and order_by are NULL.

@wush978 should work now, try it out
