ResourceCollection lookup should also search against resource_name

[leemhenson]

Hi. I hit a problem with belongs_to :foo_bar where :foo_bar refers to a resource alias:

ActiveAdmin.register Aaa::Bbb, as: "FooBar" do

As it stands, the resource is never found in the ResourceCollection and you get a lookup error. It appears belongs_to assumes the symbol is an underscored class name. I've patched the find predicate to check the resource_name as well as the resource_class when searching the collection.

What do you reckon? Is this sensible?

That whole file needs a suite of tests... For now, could you add some tests to confirm that it now works as you need it to?

Thanks for the contribution!

Oh, hold on a minute. Why did you put this on the rails4 branch? It should have been on master.

[seanlinsley]

I'm going to remove these changes from the rails4 branch. Please open a new PR for these changes on top of master.
