Fix server create for boot-from-volume

* server create required --image even when booting the server from a
  volume.  Change options to require either --image or --volume to
  specify the server boot disk.  Using --volume currently uses device
  'vda' for the block mapping and ignores any other block mappings
  given in --block-device-mapping.
* server create and server show are both affected by bug 1378842 where
  an excepion was thrown when no image ID was present in the returned
  server object, which is the case for a server booted from a volume.
* Fix the remaining assertEqual() order problems in test_server.py
