Title: Fix none column retrieve in query.

Previously none column is represented by whole object.
So changed that none column will be represented by null.

When I call this API.
https://api.usergrid.com/baasio/portal/users?limit=10&ql=select username, email, company

* 2nd data ( user2 ) is not exist company column.

- expected
```javascript
"list": [
[
"user1",
"user1@baas.io",
"BAAS"
],
[
"user2",
"user2@baas.io",
**null**
],
...
```
- actually
```javascript
"list": [
[
"user1",
"user1@baas.io",
"BAAS"
],
[
"user2",
"user2@baas.io",
{
"uuid": "779b8a0f-227b-11e2-9958-02003axxxxx",
"type": "user",
"name": "user2",
"created": 1351592445754,
"modified": 1351592445754,
"activated": true,
"email": "user2@baas.io",
"metadata": {
....
},
"picture": "http://www.gravatar.com/avatar/68e164df2d02da8360362e7bxxxxxx",
"username": "user2"
}
],
```
