refactor tests to dsl

@ianstormtaylor here is another bit of tests ported to the DSL, with a few new cases to resolve. what would you recommend? There are some inline comments with `XXX` too.

---

```js
it('should push a refresh event', function(){
  test.page();
  var item = window._qevents[1];
  assert(item.event === 'refresh');
});
```

one option, somehow skipping the first step by only saying it was called, but not specifying the arguments, but this wouldn't technically work (something like it may tho):

```js
beforeEach(function(){
  test.spy(window._qevents, 'push');
});

it('should push a refresh event', function(){
  test
    .page()
    .called(window._qevents.push)
    .called(window._qevents.push, { event: 'refresh' });
});
```

another option, specify the index:

```js
it('should push a refresh event', function(){
  test
    .page()
    .called(window._qevents.push, { event: 'refresh' })
      .index(1);
});
```

or

```js
it('should push a refresh event', function(){
  test
    .page()
    .called(1, window._qevents.push, { event: 'refresh' });
});
```

Don't like either of those b/c they're confusing?

Another option is to just test for the first item as well, which might be better (and would be helpful for future people).

```js
it('should push a refresh event', function(){
  test
    .page()
    .called(window._qevents.push, { some: user });
    .called(window._qevents.push, { event: 'refresh' });
});
```
