unproccessable entity error 422 message has blank dictionary for status

[Craig Vyvial]

To reproduce this issue just attempt to resize the flavor while the instance is in a RESIZE status.
This message should be improved and add the correct status.

RESPONSE BODY : {
    "unprocessableEntity": {
        "code": 422,
        "message": "Instance is not currently available for an action to be performed (status was {})."
    }
}
