cloudinary:sync_assets with custom static_images_dir doesn't work

[mikebaldry]

The code that works out if it should use the static hash name looks the file up in the static metadata with if type == :asset && @metadata["images/#{source}"]

my static_images_dir is set to ["assets/images/email"] as I only want email assets to be done by cloudinary.

The creates a meta data file containing paths such as emails/twitter.png, so when the meta data is looked for it doesn't find it because its looking for images/emails/twitter.png?
