Using GraphQL inheritance leads to exception

[beikov]

Description

Querying a GraphQL schema that uses interface inheritance fails when trying to use a selection set that asks for fields of the base type e.g.

query {
  myQuery {
    id
    subtypeField {
      id
    }
  }
}

Problem is that the selection set contains a path like ResultType.subtypeField/[Subtype1, Subtype2].id which we can't handle in the GraphQL query integration.
