Describe the Bug

An example speaks a thousand words. Given the following minimal test case:

import strawberry
from django.test import SimpleTestCase


@strawberry.type
class Example:
    @strawberry.field
    async def async_field_1(self) -> str:
        return "str 1"

    @strawberry.field()
    async def async_field_2(self) -> str:
        return "str 2"


class ExampleTest(SimpleTestCase):
    async def test_types(self):
        example = Example()

        self.assertEqual(await example.async_field_1(), "str 1")
        self.assertEqual(await example.async_field_2(), "str 2")

• the only difference between async_field_1 and async_field_2 is the parentheses after the strawberry.field annotation
• the test passes (demonstrated by green checkmark)
• the first assertion does not pass type check (demonstrated by red squiggly). The second one does.

Screenshot:

The problem shows up as "async_field_1 is not awaitable" (if the field has args), or "missing argument for parameter resolver" (if the field has no args)
