Daco Harkes f592a11e51 [vm/ffi] NativeFieldWrapper FfiNative check receivers for nullptr 
Changes `FfiNative` instance methods on `NativeFieldWrapperClass`es
that have `Pointer<Void>` conversion to check for `nullptr`.

If the native field has `0`/`nullptr` a `StateError` is thrown:
"Bad state: Native field is nullptr."

This only makes sense if the first native field is used to point to
the C++ object corresponding to the Dart object. As far as we know
all current use cases do so.
