Can't use queue.pop

When trying to use queue.pop with a client on 1.0 version, the client fails with the following error:

  File "/opt/stack/python-zaqarclient/zaqarclient/queues/v1/queues.py", line 198, in pop
    msgs = core.message_pop(trans, req, self._name, count=count)
  File "/opt/stack/python-zaqarclient/zaqarclient/queues/v1/core.py", line 339, in message_pop
    transport.send(request)
  File "/opt/stack/python-zaqarclient/zaqarclient/transport/http.py", line 106, in send
    raise self.http_to_zaqar[resp.status_code](msg)
zaqarclient.transport.errors.MalformedRequest: The "ids" query parameter is required.

If we bum the version to 1.1, it fails with a different error:

  File "/opt/stack/python-zaqarclient/zaqarclient/queues/v1/iterator.py", line 98, in __next__
    args = self._listing_response.pop(0)
AttributeError: 'NoneType' object has no attribute 'pop'

The first one should probably fails with a better error. The second one should just work, I think :).
