Improve unit test coverage for core classes (#4241)
Added LoginTest to cover Login inner classes. Updated FacebookConnectTest to test validateToken and cover connection request logic. Updated JSObjectTest to cover async calls with SuccessCallback. Updated ValidatorTest to cover scroll listener logic. Updated TestCodenameOneImplementation to support network mocking. Updated PickerTest to clarify coverage of inner classes.
