Without this commit, the method `saveModifiedImages` did not use
editables zone but rather the whole `$editable`.
Because of that, oeModel and oeId were undefined and saving images
was done without the proper metadata.
That made impossible the retrieval of the images from the method
`ir.qweb.field.image` `from_html` defined by the module `web_unsplash`.
