Fix Relay Connection ID

[iorlandini]

The issue

The only optimization is being aborted when using the GlobalID as expected in Relay.

Example

Given:

from django.db import models
from graphene import relay
from graphene_django_optimizer import OptimizedDjangoObjectType


class Customer(models.Model):
    first_name = models.CharField(max_length=100)
    last_name = models.CharField(max_length=100)


class CustomerType(OptimizedDjangoObjectType):
    class Meta:
        model = Customer
        name = "Customer"
        interfaces = (relay.Node,)


class Query(graphene.ObjectType):
    customers = OptimizedConnectionField(CustomerType)

And performing:

{
    customers {
        edges {
            node {
                id
            }
        }
    }
}

The following query is executed:

SELECT
    "customer_customer"."id",
    "customer_customer"."first_name",
    "customer_customer"."last_name",
FROM
    "customer_customer";

Expected:

SELECT
    "customer_customer"."id"
FROM
    "customer_customer";

Hi @tfoxy, any chance to get this reviewed?

[tfoxy]

Thanks for taking time for this. v0.7.1 released with this fix! Sorry it took so long.

Do not worry about the delayed answer, also, thank you for writing the module in the first place. Anyway, I have been using my own fork.

On the other hand, I created another PR to fix another issue #57. Again, I'm using it from my own fork. But I think it would be good to fix it in this repository as well.
