[FIX] web_editor: relative URL in background snippet

When the backround is set with the media modal, directly get the URL of
the IMG element (equivalent to `.getAttribute('src')`) instead of doing
`.src` which returns absolute URI.

This fix uses jQuery wrapper so it still works if called with object:

  $({src: 'test.jpg'}).attr('src') === 'test.jpg'

note: before 17237ff31 we already used `.attr('src')`.
