undefined method `each' for nil:NilClass when iterating over empty response

[aleccarper]

Hello,

I've recently encountered an error that occurs while trying to iterate over orders, or simply checking the count of orders, when no orders are returned. I have tracked this down to line 39-41 of paged_ecwid_response.rb:

    response.body["items"].each do |item|
      yielder << block.call(item)
    end

If this block is moved below where count, offset, and total are set and then wrapped in an if count > 0 both iteration and count checks work as expected.

cool, good find. i'd be happy to accept a PR from you with the fix!
