Default scopes don't work

Problem/Motivation

This module adds a "Default scopes" option to the consumers form:

https://git.drupalcode.org/project/simple_oauth_password_grant/-/blob/2....

But it doesn't use this anywhere in its own code.

Maybe this worked in the past, but it doesn't work anymore.
