Make sure that Social Media System can be correctly uninstalled

Problem/Motivation

We introduced new module Social Media System at https://www.drupal.org/project/social/issues/3402176 →
We also added additional configuration here: https://www.drupal.org/project/social/issues/3403980 →
It is important to make sure that module can be safely and correctly uninstalled.

Some discussions points:
- should we enforce media teaser view mode dependency on Social Media System
- should we enforce media file field dependency on Social Media System
