Create a page. Try to copy / move this page in another location, where a page already exists.
- Copy will give a warning and allow to overwrite or change target
- Rename will give an error
We should have a consistent way of handling the "already exist" use case.
Note: #core.create.page.error.docalreadyexists# does not appear anymore. if you want to create a page that already exists, XWiki opens the page in edit mode.
