can’t handle documents without type property

[gr2m]

the type property is optional at Hoodie, for example

hoodie.store.add({foo: 'bar'})

creates a document like this

{
  "foo": "bar",
  "updatedAt": "2016-07-26T23:44:14.429Z",
  "createdAt": "2016-07-26T23:44:14.429Z",
  "id": "95BE9F30-F217-F061-93FD-D3F9F5799CAD",
  "_rev": "1-fa563dd8cbff83f6e77d4c9b18a57980"
}

If I’d do the same in an app using ember-hoodie, I get this error

vendor.js:26604 Uncaught (in promise) EmberError {description: undefined, fileName: undefined, lineNumber: undefined, message: "Assertion Failed: You need to pass a model name to the store's normalize method", name: "Error"…}

I’d suggest we simply ignore documents without a type property
