We are creating more than 1 photo in other parts of the contacts app, thumbnails for specific use in sms, call log, etc.

https://github.com/mozilla-b2g/gaia/blob/master/apps/communications/contacts/js/utilities/image_thumbnail.js

And we store it in specific positions in the photo array, original photo at 0, thumbnail at 1.

Again, not blocking in this patch but we can fill a follow up.
