Only not work with relay node

[syfun]

First, thanks for this library😁.

When used with relay node, I found only optimize not worked. And the reason maybe this:

graphene-django-optimizer/graphene_django_optimizer/query.py

Lines 210 to 215 in 8968470

	def _is_resolver_for_id_field(self, resolver):
	resolve_id = DjangoObjectType.resolve_id
	# For python 2 unbound method:
	if hasattr(resolve_id, 'im_func'):
	resolve_id = resolve_id.im_func
	return resolver == resolve_id

resolver is functools.partial and it's func is GlobalID.id_resolver, it's args[0] is DjangoObjectType.resolve_id.

Environment:
Python: 3.7.3
Django: 2.2.1
