Fix quota show --default command

Work around a bug in OpenStack SDK 0.9.11 and 0.9.12 that causes
quota show --default to fail.  This can be removed when the proposed
SDK fix (https://review.openstack.org/420301) is reelased and in the
minimum SDK version in global requirements.

quota set --network is still broken, I can't fix it at the moment...
