solidus

Hi
I have updated Solidus to 3.2.7 from 3.0 :sweat_smile:
I've looked into <https://guides.solidus.io/customization/subscribing-to-events#upgrading-from-the-legacy-event-system>
We didn't use `Spree::Event` and I cannot any `config.use_legacy_events` in my code, but I'm getting the following warning:
```DEPRECATION WARNING: Your Solidus store is using the legacy event system. You're
encouraged to switch to the new event bus. After you're done, you
can remove the `use_legacy_events` setting from `spree.rb`.```
Please, point me out what is wrong?

I think I have found where this config is defined:
`..\solidus_core-3.2.7\lib\spree\app_configuration.rb`
```versioned_preference :use_legacy_events, :boolean, initial_value: true, boundaries: { "3.2.0.alpha" =&gt; false } ```

It seems to be is TRUE by default. :disappointed_relieved:

My understanding with deprecations is that if you assign that config value to false in your project, if events are still working, then the new events system is compatible so you can keep the change.

Edit: config should be false for legacy_events to test the new system
