Fix bug when retrieving field values

[njt1982]

This seems to fix #22

Field Collections and Text now seem to work...

For this query:

query {
  node(nid:"6") {
    nid
    title
    field_teaser_text {
      value
      format
    }
  }
}

Before:

  "data": {
    "node": [
      {
        "nid": "6",
        "title": "EXAMPLE",
        "field_teaser_text": {
          "value": null,
          "format": null
        }
      }
    ]
  }

Now:

  "data": {
    "node": [
      {
        "nid": "6",
        "title": "EXAMPLE",
        "field_teaser_text": {
          "value": "Some teaser text value",
          "format": "filtered_html"
        }
      }
    ]
  }

One issue... if I do:

query {
  node(nid:"6") {
    nid
    title
    field_topics {
      tid
    } 
  }
}

This field has 7 topics, but obviously we're only returning the first one?

  "data": {
    "node": [
      {
        "nid": "6",
        "title": "EXAMPLE",
        "field_topics": {
          "tid": "16"
        }
      }
    ]
  }

@njt1982 first, great work

I belive that we can access raw value with ->raw()

$wrapper->body->raw();

Very good article about entity metadata wrapper Death to Field Arrays!

I think I tried ->raw() and it returned the same single value instead of the raw field properties... I’ll have to try it again 😉
