When you open the image modal of the website editor the selected image
is the current image.
But if the image is not an attachment with an `url` field set (eg. it
has been uploaded and is not a file in a /static/ folder) the match
between image modal and current did not work and to close it we need to:
- actively select the current image then click "Save"
- use the X button to close the modal without saving
With this changeset, the match of current image with image list is done
on the attachment `url` and if unavailable with /web/image/ID/name.jpg
path which cover both possibilities.
