public function DatabaseLegacyTest::testDbDropField in Drupal 8

Tests deprecation of the db_drop_field() function.

@expectedDeprecation db_drop_field() is deprecated in drupal:8.0.0. It will be removed from drupal:9.0.0. Instead, get a database connection injected into your service from the container, get its schema driver, and call dropField() on it. For example, $injected_database->schema()->dropField($table, $field). See https://www.drupal.org/node/2993033
