Title: Change `#set_order_shipping_method` to work with current Spree

The [documentation](http://api.spreecommerce.com/v1/orders/#selecting-a-delivery-method) says the `shipping_method_id` has to be on the toplevel params hash, but that's not how Spree implements it.

This change makes the call work with the current spree (1.3.2)
