Manager.acreate: model isn't type checked

[jlost]

from django.db import models

class Thing(models.Model):
    id = models.AutoField()

def create_thing_sync(name: str) -> None:
    Thing.objects.create(name="This line shows an error")

async def create_thing_async(name: str) -> None:
    Thing.objects.acreate(name="This one doesn't")

Error only appears for the first example, but it should show for both:

mypy thing.py
Unexpected attribute "name" for model "Thing"

I think the problem is in the mypy plugin. I'll take a look when I get the chance.
