Title: JSONSerializer normalize each record passed to extractArray

`extractArray` was expecting a hash but arrays are passed to its payload argument.
Implementation was documented, so this is just a copy/paste PR.

This fix issues with [ember-localstorage-adapter](https://github.com/rpflorence/ember-localstorage-adapter) that was not able to deserialize numbers / dates properly.
