Function that has dependecies cannot be registered when using future annotations

[nrbnlulu]

Example:

from __future__ import annotations
from dataclasses import dataclass

@dataclass
class  B:
    a: A

def get_b(a: A) -> B:
    return B(a)

class A: ...

cont = aioinject.Container()
cont.register(
    aioinject.Object(A()),
    aioinject.Singleton(get_b)
)
