Title: Replace "=" with "||=" in create_fixtures method

Replaced `=` with `||=` operator in `create_fixtures` method, otherwise the values of the parameter `class_names` seem to be overwritten and ignored. This solves for me the issue #2572 i had with

```
set_fixture_class 'admin/known_ips' => Admin::KnownIP
```

I have not tested this patch, please review. It looks to me like it was a typo.

I am not closing Issue #2572 yet because i am not sure this "typo" explains all the strange behavior.
