Better error handling on resource arrays

[mhevery]

This should produce a better error!

I have problem with $resource and arrays. I have forked angular-seed
to test my problem in isolation:
https://github.com/witoldsz/resource-query-arrays

---

Controller:

function MyCtrl1($resource) {
var Item = $resource('items')
this.items = Item.query();
}
MyCtrl1.$inject = ['$resource'];

---

Scenario:

describe('MyCtrl1', function() {
var scope, browser, xhr, myCtrl1;

beforeEach(function(){
scope = angular.scope();
browser = scope.$service('$browser');
xhr = browser.xhr;
});

it('should ....', function() {
xhr.expectGET('items').respond(['item1','item2','item3']);
myCtrl1 = scope.$new(MyCtrl1);
xhr.flush();
expect(myCtrl1.items).toContain('item1');
});
});

---

Test result:

F.
