public function DatabaseLegacyTest::testDbAddIndex in Drupal 8

Tests deprecation of the db_add_index() function.

@expectedDeprecation db_add_index() is deprecated in drupal:8.0.x and will be removed in drupal:9.0.0. Instead, get a database connection injected into your service from the container, get its schema driver, and call addIndex() on it. For example, $injected_database->schema()->addIndex($table, $name, $fields, $spec). See https://www.drupal.org/node/2993033
