Currently, there is an error when you try to view content with a broken URL alias in the backoffice.
Known issues on breaking aliases:
https://issues.ibexa.co/browse/IBX-4326 -> fixed already
https://issues.ibexa.co/browse/IBX-3957

Expected result
Log the exception but make the content available to edit.

Note
Even though the URL alias has some issues, the content item should be accessible in the administration interface.
This is the reason why we use different URLs in the admin. So the content is always accessible.
It won't solve the error with the URL but at least the user/admin can access the content and manage URLs in the administration interface
