title: With GraphQL + Apollo Client, how to return a totalCount after mutating?
body: <p>I have the following:</p>
  
  <pre><code>const typeDefs = `
  type Request {
    id: ID!
    email: String!
    totalCount: Int
  }
  
  type Mutation {
    createRequest(email: String!): Request!
  }
  `;
  
  export default typeDefs;
  </code></pre>
  
  <p>Right now totalCount is returning null. Using GraphQL, what is the right way to return the TotalCount as the mutation's response. Should totalCount be included somehow in the Request model?</p>
