Fix local Add-on restore on blank instance (#3403)

Make sure to not reference version attribute from the DockerAddon
instance since it is not yet populated in case this instance hadn't
installed that Add-on previously.

Use the higher level Images.load() API which returns a list of images
instead of loading with the lower level API and then search for the
image we just imported.
