Broken local images or attachments after Rename

Issue reported by wakeel on the forum, see https://forum.xwiki.org/t/rename-move-broken-image/5040

Steps: 

• Create a page 'Test'
• Using the WYSIWYG, add an image
• The wiki syntax will be:

  [[image:image.png]]
    

• Save the page
• Use the 'Move/Rename' from the content menu
• Use 'Test1' as the new title
• Visit the new page. The image is broken
