Workaround for iOS engine on macOS 10.14

The documentation claims that the AVFoundation based frameworks are
available from macOS 10.14 onwards, but the API for getting the voices
returns nothing.

Handle that in the test case for now. Ideally, our plugin infrastructure
would allow plugins to report such conditions so that the respective
engine gets ignored.
