updating angular 1.2 resource

* changed IResource and IResourceClass `query` signature to return `IResource[]` matching [angular 1.2.0](https://github.com/angular/angular.js/blob/v1.2.0/src/ngResource/resource.js#L292) [documentation](http://docs.angularjs.org/api/ngResource.$resource#example)
* removed IActionCall interface from angular-resource (allowing a direct way to change the signature for query)
* added missing angular-resource-tests
