Title: Remove array() when serialize an item resource in JsonApiSerializer

According the JSON API specification an individual resource SHOULD be represented as a single "resource object" (described below) or a string value containing its ID (http://jsonapi.org/format/#document-structure-resource-representations).

So I changed JsonApiSerializer to represent single item as single oblect.
