Title: Fix a NPE when the expected array is actually null

Don't crash with a NPE when the expected array is actually null, just return null.

```json
{
"success": true,
"data": {
"user": 3,
"own": null,
"passes": null,
"completed": null
},
"version": 1371160528774
}
```

Without this fix, the path `$.data.passes[0].id` gets a NPE.
