It's impossible to confirm the renaming of pages in subwikis

Steps to reproduce:

• Create a page on a subwiki. Edit it with the class editor and add a property.
• Add another page on the subwiki and add an object of that XClass to it.
• Rename the XClass. When the question if the XClass shall be renamed, select everything and confirm the renaming.

Expected result:

The XClass is renamed.

Actual result:

Nothing is renamed.

This same bug most likely affects all job questions that involve selecting documents.
