Version 1.2 breaks config import due to incompatible schemas

Problem/Motivation

After applying the update to 1.2 and configuring the content types, running a config import breaks with the following error:

The import failed due to the following reasons:

Unexpected error during import with operation update for orange_dam.settings: The configuration property content_types.Audio Container.use_datatable doesn't exist.

Steps to reproduce

1. Update orange_dam module.
2. Configure the content_types to either use or not use_datatable
3. Import your new config.

Proposed resolution

Add update hook to modify the user's stored schema to mirror the new schema.
