Bug 1060729 - Handle default outgoing call SIM set to always ask in ICE ...

...contacts
This test can be merged with 'calls dial when ICE Contact is dialed'.
Please also use this pattern to make sure we call with the good SIM:
```js
[0, 1].forEach(function(cardIndex) {
  test('calls dial for ICE contacts on SIM ' + cardIndex', function() {
    […]
    sinon.assert.calledWith(navigator.mozTelephony.dial, num, cardIndex);
  });
});
```
