Fixes:
Xamarin.Mac.Tests.DelegateAndDataSourceTest
[FAIL] DelegateAndDataSourceAllowsNull : 1 failing types
1 failing types:
PassKit.PKPaymentAuthorizationViewController: Could not initialize an instance of the type 'PassKit.PKPaymentAuthorizationViewController': the native 'init' method returned nil.
It is possible to ignore this condition by setting ObjCRuntime.Class.ThrowOnInitFailure to false.
