Restoring a page on a subwiki restores it on the main wiki instead

Steps to reproduce

1. Create a subwiki W1
2. Create the page A inside subwiki W1
3. Delete the page A

Expected result

• Get redirected to page A in view mode and see the restored title and content

Actual result

• Redirected in to page A in view mode the "document does not exist" information is displayed and the document is not restored.
• If you look at the page A inside the main wiki, you will see that it was restored there instead.
