For completeness should we make this test case a UNIT_TEST_CASE create the
native port without any isolates and then create an isolate and do the
invokestatic business.

I don't understand why this helps.

This ties back to my comment regarding Dart_NewNativePort(...) not requiring an
Isolate to be present.

We want to test that Dart_NewNativePort works even when there is no current
Isolate and hence my suggestion to turn it into a UNIT_TEST

I now test in both configurations.
