Contacts sort order not working or only working with detailed name. #4985
Description
Describe the bug
Add a contact -> Type in name "John Shaft" -> Save -> Change settings "sort contacts by last name" -> Contact turns up as "John Shaft" not "Shaft, John".
Works properly only if "detailed name" is added to the contact.
I don't think it's a great idea to only have a single name field exposed in the UI in the first place.
But If you want to keep this at least make it work properly so that sort order adjustments do not "silently" fail! For example, add some intelligence so that it splits up things that you enter there into first and last name if it is only two words.
Also I have no clear mental mondel, as probably most users, what happens if that singular name field is different from the detailed name field.
Steps to reproduce
Add a contact -> Type in name "John Shaft" -> Save -> Change settings "sort contacts by last name" -> Contact turns up as "John Shaft" not "Shaft, John".
Expected behavior
Contact turns up properly sorted.
Actual behavior
No effect of sort order.
