Attachments in object content is not displayed if a redirect xobject is present

Reproduction steps:

• Create a new page with a AWM.Content xobject
• Upload a new image in the page and insert it in the xobject (either directly in the editor or in two steps)
• Add a redirect xobject to another page
• Open back the page with the editor xobject and check the AWM.Content xobject

Expected result:

• the editor displays the attached image

Obtained result:

• the editor only displays the reference of the image
• Trying to display the source of the content returns "The service used by the CKEditor source plugin to convert between HTML and wiki syntax."
• When checking the HTML we can see that the URL is good and leads to /download/ action with the reference of the current page, but following this leads to /download/ action to the redirected page

Note that the problems also appears when the xobject content is used programmatically in another document.
