Node#remove_namespaces! breaks Node#>

#! /usr/bin/env ruby

require "rubygems"

xml_with_ns = <<-EOXML
<?xml version="1.0" ?>
<root xmlns="http://foo.example.com/">
  <aaa> <bbb /> </aaa>

doc = Nokogiri::XML(xml_with_ns)
doc.remove_namespaces!
doc.xpath("//aaa").each do |node|
  puts (node > "bbb").inspect
  # => []
end

# for comparison
doc = Nokogiri::XML(xml_without_ns)
doc.xpath("//aaa").each do |node|
  puts (node > "bbb").inspect
  # => [#<Nokogiri::XML::Element:0x3f8bc3581e28 name="bbb">]
end

I believe we can address this if #remove_namespaces! adds the document's default namespace to each node. Or else, remove the document's default namespace. Pick one.

Node#remove_namespaces! now removes namespace declarations as well. Closed by 543901e.
