Invalid path/type on unknown nodes

[Maximilien-R]

When requesting unknown fields on a GraphQL query, the path contained on errors doesn't seems to be properly re-calculated. Also, the type from the error message is invalid too:

type UserStatsViews {
  total: Int
}

type UserStats {
  views: UserStatsViews
}

type User {
  name: String
  stats: UserStats
}

type Query {
  viewer: User
}

Query example:

query {
  viewer {
    name
    stats {
      views {
        total
        unknownField4
      }
      unknownField3
    }
    unknownField2
  }
  unknownField1
}

Result:

{
  "data": null,
  "errors": [
    {
      ...
      "path": [
        "viewer",
        "stats",
        "views",
        "unknownField4"
      ]
    },
    {
      ...
      "path": [
        "viewer",
        "stats",
        "views",
        "unknownField4",
        "unknownField3"
      ]
    },
    {
      ...
      "path": [
        "viewer",
        "stats",
        "views",
        "unknownField4",
        "unknownField3",
        "unknownField2"
      ]
    },
    {
      ...
      "path": [
        "viewer",
        "stats",
        "views",
        "unknownField4",
        "unknownField3",
        "unknownField2",
        "unknownField1"
      ]
    },
  ]
}

The result is different depending on using fragment or not.
