 * Implements hook_uninstall().

 * Although not strictly necessary for testing, it is good practice to tidy up
 * module config and content on uninstalling. Plus, when developing this module
 * and enabling it manually as a real module, this code is needed to clean up,
 * otherwise a re-install fails.
 *
 * The entity types, custom fields and storage are deleted automatically by
 * having 'enforced: module: - scheduler_api_test' in the config/install/*.yml
 * files. However, we have to delete the actual entity content here.
