Fix more double logging in ActiveRecord::QueryLogs

ref: rails#46279

That PR missed the case where if you set `config.active_record.query_log_tags = [:namespaced_controller]`, it would log the controller twice:

```
/*namespaced_controller:Foo::BarController,controller:bar*
```

So this PR just fixes that bug, and tweaks the changelog entry rather than adding another one for the same bug.
