Title: fixes failing tests (undefined method model_name' for Fixnum:Class)

The test should pass with those commits...

Turns out that, when using named/polymorphic route helpers, you cannot pass ids as arguments.
The id should be passed with :id hash key.

Even though the tests pass, I have yet to test a "real" active_admin instance.
