The failure is because await devices.workingDevice requires a physical device, and we were running it using Mac name under .ci.yaml.

There are 3 possible fixes:

1. running on simulator. Use testWithNewIOSSimulator to get the device ID, and run the simulator. In this case we don't have to set deviceOperatingSystem because it's only for physical device.
2. actually running it on physical device (This PR)
3. change this test to flutter_drone test which runs on simulator too, but it is a lot more involved (moving the test from devicelab to flutter_drone).

We pick option 2 because it's relatively easier, and we may actually want to test platform views on device (e.g. measure performance, etc).
