Rails 7.1 - error when multi_tenant defined in abstract class

After updating to Rails 7.1, I'm getting this error when running my tests:

```
TypeError:
no implicit conversion of nil into String

```

I've tracked it down to this definition of `multi_tenant` in the parent abstract class:

I can confirm that MultiTenant.current_tenant is set. Moving the method directly to the subclass causes it to start working again. Removing the `multi_tenant` method will give me the expected invalid model (because the organization is nil).

I'm not seeing anything about this in the changelog... am I missing something?
