Drupal\Core\Entity\EntityMalformedException regression caused by 3477436

Problem/Motivation

The post_update implemented in 🐛 Uninstalling Module is not removing image styles image.style.cke_media_resize_large Active assumes the image style configs exist. In cases where those image styles have been deleted (we don't use them on our sites), the update re-creates the config items, but with the dependency only, e.g.

dependencies:
  enforced:
    module:
      - ckeditor_media_resize

None of the other image style config is present. If you then visit /admin/config/media/image-styles, you get the fatal error below, because the resurrected configs items are indeed malformed.

- Visit the Image Styles page.

Proposed resolution

Modify the post_update hook to do nothing if the configs do not exisit.
