Update 8302 fails when the config is already updated

The proposition as a patch.

The proposition fixed (wrong condition).

I am not against this per-se. But it suggests that you run things in the wrong order.
Check drush deploy for the standardized form.

You have to run database update hooks before anything else. And then you import config, which will bring the changed one from your development environment.

I added a check to see what the mode is to make sure the update fails if you do something silly.
