Title: Remove in forms images deleted from within the wordpress media frame.

This concerns image fields.
When you click “delete permanently” from within the wordpress image properties popup (after have clicked the "edit image" icon) , then close the popup, the image stays in the form, although it was removed from the Wordpress library.
If you then click “Update” it’ll result in a grey box in place of the original image.

This commit fixes this issue.
