Title: Allow parsing null pushed_at

Repository's pushed_at ia an attribute which can be null. If it is null, you'll get a following error message.

```
parsing time "null" as ""2006-01-02T15:04:05Z07:00"": cannot parse "null" as """
```

I changed the test to fail for such a situation and passed by changing PushedAt to be a pointer.
