queries for newly created imagesets are not translated

To reproduce:

• create a new project
• create a new imageset using the Essentials gallery manager
• go to the cms, open the "images" section
• create a new folder, you'll see an untranslated item (see screenshot)

The 10.2 code relied on the translation nodes being copied as part of copying the "new-image" and "new-image-folder" query trees. I'd suggest to improve this a bit and write the name of the image set, or else you may end up with multiple menu items with the same name.
