I ran the same test locally on a container built with the jobara:GH-2106.

I was no longer able to duplicate any of the errors when running php artisan app:refresh-dev

As a note, I wasn't able to test the case from the settings function where the table doesn't exist. I could drop the table, but it was causing other tests to break, so I've left it off. Hence the drop in coverage.
