During the creation of a page, if the "office" type is selected, you can create a terminal page with no parent

1. Go to create action
2. Select the "office" type (the OO service must be connected before)
3. Set a title, but with no parent
4. Click "create terminal page"
5. Click on create

The live validation displays an error on the page. However, the page is redirected to the OfficeImporter UI with an incorrect target page.
