GraphQL response doesn't include id

[Sushil Singh]

Steps to reproduce

1. Generate app, authentication. (https://generator.feathers-plus.com/get-started/)
2. Follow guide and add email and password field to user schema.
3. Generate graphql (with auth)
4. Run the app and create new user and access token.
5. Open GraphiQL and Set Authorization Header with access token.
6. Run query.
   { findUser(query: {}) { id email } }
7. Response should contain id for the record but id is null

{
  "total": 1,
  "limit": 10,
  "skip": 0,
  "data": {
    "findUser": [
      {
        "id": null,
        "email": "[e-mail]"
      }
    ]
  }
}

8. Change id to _id in users.schema.js and re run feathers-plus g all or feathers-plus g graphql.
9. Run app now and run above query with _id. Response will have _id with correct value.
10. Example given in get-started guide is not consistent if mongoose is used. I couldn't find any mongoose example in @feathers-plus/cli-generator-example.
11. Generator should use _id if mongoose is selected as db.

You have to define a _id: { type: 'ID' } field in your model if your id field is named _id. The generator does not change the name of index fields based on the type of adapter the service uses.

I think this should be documented.
