Reporter's onSpecComplete is called after onRunComplete

Reproduced on this test.js:

``` javascript
function wait(millis) {
var startTime = new Date().getTime();
while (new Date().getTime() < startTime + millis) {}
}

describe("suite", function () {
it("wait 1 sec", function () {
wait(1000);
});
it("wait 11 sec", function () {
wait(11000);
});
it("wait 1 sec again", function () {
wait(1000);
});
});
```

Test `wait 11 sec` takes 11 sec to execute, so the browser is disconnected:

```
WARN [Chrome 38.0.2125 (Linux)]: Disconnected (1 times), because no message in 10000 ms.
```

The problem is that, for some reason, `onSpecComplete` is called after `onRunComplete`.
Is it expected or a bug?
