Issue Summary

When using the sidebar menu to rename a page, it is possible to give the same name as an archived page (whereas this is not possible when creating or modifying a page)
moreover, if we unarchive a page, it can have the same name as an existing page on the tree.

Steps to Reproduce

1. Create a page with the title "abcd" and publish it.
2. Archive this page
3. Create a new page with title "abcdtest" and publish it 
4. Rename this page from the sidebar menu to "abcd"
5. Unarchive the other page

Expected Results

It should not be possible to create/rename pages with the same title.

Actual Results

When we rename the page from the sidebar, it is not validating the duplicate check for archived pages.

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
