Slugs are generated for Singles on creation, but not updated on edit.

Description

Even though slugs aren’t technically used by singles, that attribute is still created and populated on creation. A bit nice because if you’re finding an entry, you can use the same API (slug => 'xyz'), no matter which section type.

But, that Single's slug isn't updated whenever you edit it's title or URI.

This may not be a bug at all, but more of a question on whether it should be updated or not, or at least something to note if #3368 ever happens. It just seems odd that the attribute lives there but is never touched after creation.

Steps to reproduce

1. Create single.
2. View the slug attribute for that single.
3. Edit single.
4. Observe unchanged slug.

Additional info

• Craft version: 3.1.6
• PHP version: 7.1.24

We’re planning on making Single entry slugs editable in Craft 3.2 (#3368) so this won’t be awkward anymore at that point.
