Forward references break with NamedTuples

[khusmann]

Problem Description

Thanks for this library! Hopefully this is an easy one: Forward references inside NamedTuples do not get resolved and result in a warning

Steps to reproduce the behavior:

from __future__ import annotations
from typing import NamedTuple

class Foo(NamedTuple):
    b: Bar

class Bar:
    pass

Results in:

Warn: Error parsing type annotation ForwardRef('Bar') for bug.Foo.__init__. Import of Bar failed: name 'Bar' is not defined

It appears to just be NamedTuples -- regular classes (and dataclasses) do not produce this warning.
