Yes, when calling a method like this, it was throwing a `NoMethodError`:

```
  1) Octopus::Association when you have a 1 x 1 relationship should include models
     Failure/Error: Computer.includes(:keyboard).find(c.id)
     NoMethodError:
       undefined method `keyboard_without_octopus?' for #<Computer id: 89, name: "Computer Brazil">
     # ./lib/octopus/rails2/association.rb:14:in `block in association_accessor_methods'
     # ./spec/octopus/association_spec.rb:56:in `block (3 levels) in <top (required)>'
```

Honestly, this test is just a replication of the original error I was seeing, it's probably not the best way to test this change. If you have a better suggestion, I'm all ears.
