The option Preserve children appears at the end of the move/rename process of a page that does not have child pages

I think the usability bug is that even though the user moves/renames the terminal page (it's important due to this change), XWiki still displays "Preserve children" in result of refactoring.

My steps on XWiki 16.10.8 and 17.4.0:

1. Make yourself an advanced user
2. Create a terminal page in XWiki
3. Run the move/rename, change the name of the current page to something else
4. Click "Rename"

Actual result

The operation will succeed, but "Preserve children" will be shown as unselected in result of operation

Expected result

The user does not see "Preserve children" because the renamed page is a terminal page.
