Fix debugging for simulator when --emulator is not passed

When --emulator is not passed, CLI will try to debug on iOS Simulator in case there's one started (or CLI will start it).
However the iOS debug service calls methods for debug on device and it fails.
Use correct methods when the detected devices is emulator.
