Active Job: Correctly use the desired test adapter in tests

+*   All tests now respect the `active_job.queue_adapter` config
+
+    Previously if you had set `config.active_job.queue_adapter` in your `config/application.rb`
+    or `config/environments/test.rb` file, the adapter you selected was previously not used consistently
+    across all tests. In some tests your adapter would be used, but other tests would use the `TestAdapter`.
+
+    In Rails 7.1, all tests will respect the `queue_adapter` config if provided. If no config is provided,
+    the `TestAdapter` will continue to be used.

+    See [#48585](https://github.com/rails/rails/pull/48585) for more details.

 *   Make Active Job transaction aware when used conjointly with Active Record.
 
     A common mistake with Active Job is to enqueue jobs from inside a transaction,
