Bug 1093583 - [DSDS] Add test to make a phone call with default SIM

In the Gaia unit tests, we use the following pattern for testing DSDS:
```js
[0, 1].forEach(function(serviceId) {
  test('dialer dsds make phone call with default sim: ' + serviceId, function() {
    // use serviceId for some test
  });
});
```
Could we do that here as well?
