ComplexityRoot in the generated file is wrong when binding to ID

[stobita]

Expected Behaviour

I would like to prepare a Resolver for id in the query and return the ID value of model in another field.

Actual Behavior

From Version 0.8, setting it makes the ID field duplicated in ComplexityRoot in generated.go.

type ComplexityRoot struct {
	Mutation struct {
		CreateTodo func(childComplexity int, input NewTodo) int
	}

	Query struct {
		Todos func(childComplexity int) int
	}

	Todo struct {
		ID   func(childComplexity int) int
		ID   func(childComplexity int) int
		Text func(childComplexity int) int
		Done func(childComplexity int) int
		User func(childComplexity int) int
	}

	User struct {
		ID   func(childComplexity int) int
		Name func(childComplexity int) int
	}
}

Minimal graphql.schema and models to reproduce

schema.graphql

type Todo {
  id: ID!
  todoId: Int!
  text: String!
  done: Boolean!
  user: User!
}

gqlgen.yml

models:
  Todo:
    model: gqlgen-sand/models.Todo
    fields:
      id:
        resolver: true
      todoId:
        fieldName: ID

models/todo.go

package models

type Todo struct {
	ID   int
	Text string
	Done bool
}
