Use description, not described class

The described class is overridden by rspec-rails's controller block,
which creates an anonymous controller. See:

Currently when a parent_node containg no children the xml parser return chil as nil
For ex: <?xml version="1.0" encoding="UTF-8"?><ssh_keys>  <ssh_key>    <links>      <link rel="self" href="/api/clouds/2/ssh_keys/8FA8RQF2MRS1C"/>      <link rel="cloud" href="/api/clouds/2"/>    </links>    <actions></actions>    <resource_uid>rightscale_test_eu</resource_uid>  </ssh_key></ssh_keys>
is parsed as
[{"links"=>[{"rel"=>"self", "href"=>"/api/clouds/2/ssh_keys/8FA8RQF2MRS1C"}, {"rel"=>"cloud", "href"=>"/api/clouds/2"}], "actions"=>nil, "resource_uid"=>"rightscale_test_eu"}]
notice "actions"=> nil doesnt match json as json returns "actions"=> []
