Title: Fix by adding deeper loop to unserialise meta values

After fix serialized array in meta value is properly expanded:

```json
{
"post_meta": {
"has_array_of_array": [
[
0,
1,
2,
3,
4,
5
]
]
}
}
```

Now using `&$variable` reference instead of array indexes (should be more
memory efficient and is easier to write).
