Issue: Local dev server reads undefined when using nested arrays in query

[Tenrys]

With this Prisma schema:

model Customer {
  uuid      String   @id @default(uuid())
  firstName          String        @default("")
  lastName           String        @default("")
  email              String        @unique
  phoneUuid          String
  phone              Phone         @relation(fields: [phoneUuid], references: [uuid])
}

And this query:

query MyQuery {
  listCustomers(where: { 
    OR: [
      { firstName: { contains: "bla" } }, 
      { lastName: { contains: "bla" } }
    ] 
  ) {
    uuid
    firstName
    lastName
    email
    phone {
      number
    }
  }
}

GraphQL Yoga seems to be receiving the parameters incorrectly, returning an empty result since Prisma can't understand the request:

{
    "data": {
        "listCustomers": []
    }
}

I've tried deploying onto AppSync itself and the query does function over there, so I think it may be some slip-up related to the development server.

Fix will be released as part of 1.0.0-rc.5.
