FIX: Permalink.create didn't work as expected anymore (#29895)

Browse Source 
This moves the logic of setting the correct permalink values back into the controller. And it replaces the validation with a simpler one, that always works, even when the model is loaded from the DB.

Follow-up to #29634 which broke import scripts and lots of documentation on Meta.
