Fix for issue #620 where allOf fails to process load properties with external $ref
sample:

{
  "allOf": [
    {
      "$ref": "./pet.json"
    },
    {
      "type": "object",
      "properties": {
        "mother": {
          "$ref": "./pet.json"
        }
      }
    }
  ]
}

This PR fixes the issue where pet.json under properties fails to load.
