TypeError: How to resolve fields with ListField(GenericReferenceField())?

I'm attempting to use `GenericReferenceField` or `GenericLazyReferenceField` fields in combination with `ListField`. However, it seems that the fields cannot be resolved correctly. I have the following model and graphene schema defined:

Model:
```
from mongoengine import ListField, Document, GenericReferenceField

class AndroidApp(Document):
...
generic_field_list = ListField(GenericReferenceField())
...
```

Schema:
```
import graphene
from graphene.relay import Node
from graphene_mongo import MongoengineObjectType
from graphql_jwt.decorators import superuser_required
from model import AndroidApp

class AndroidAppType(MongoengineObjectType):
class Meta:
model = AndroidApp
interfaces = (Node,)

class AndroidAppQuery(graphene.ObjectType):
android_app_list = graphene.List(AndroidAppType,
object_id_list=graphene.List(graphene.String),
name="android_app_list")

def resolve_android_app_list(self, info, object_id_list):
return AndroidApp.objects(pk__in=object_id_list)
```
Whenever I add the `ListField(GenericReferenceField())` the following stack trace occurs which says that the field cannot be resolved. A ListField in combination with `LazyReferenceField` works with the same model but not with the `GenericLazyReferenceField` or `GenericReferenceField` classes.

Stacktrace:

TypeError: AndroidAppType fields cannot be resolved. Expected Graphene type, but received: .
```

What is the intended way of using `GenericReferenceField` with `ListField`? I guess according to #70 it should be supported to use the `GenericReferenceField`.
