False query string parameters removed

This method is used in url_for (therefore in redirects as well).

If you pass a query string parameter to a url route that is false, before Rails 3.1, the generate method would reject it.

This causes issues on the redirected page if you are depending on the param to be have a specific value.

In Rails 3.2 they remove params.reject! {|k,v| !v.to_param} altogether.

So every single param you send is a string.
