Root level array causes TypeError

[philsturgeon]

Hey there! I've hit a bit of an issue, and at this time I'm not sure how to fix it. I'll dig in soon, but on the off-chance you're aware of the problem (or anyone else notices things) here it is.

  1) Invalidations::IndexController GET /invalidations has a valid contract
     Failure/Error: expect(result).to match_response_schema('invalidations')

     TypeError:
       wrong element type Hash at 0 (expected array)
     # /usr/local/bundle/gems/json_matchers-0.7.1/lib/json_matchers/payload.rb:19:in `to_h'

     # ./spec/requests/invalidations/index_spec.rb:19:in `block (3 levels) in <top (required)>'

Standard test:

    it 'has a valid contract' do
      result = JSON.parse(response.body)['result']
      expect(result).to match_response_schema('invalidations')
    end

That invalidations file:

{
  "type": "array",
  "items": {
    "$ref": "invalidation.json"
  }
}

Is this due to the top level object being an array instead of a hash?

Could you pull down #61 and try it out?
