Title: Guard against NoMethodError for image.name in image list

Image lists containing images with empty names cause knife to fail.

$ knife openstack image list
Exception: NoMethodError: undefined method `downcase' for nil:NilClass

Fixed by including to_s method prior to the downcase method on image.name.
