ForwardRef not unwrapped for inner quoted types in arguments

[Terrance]

Expected behavior

ForwardRef wrappers to be removed from argument type annotations, as per 8702f62.

Actual behavior

For arguments, the wrapper is removed only if the entire type is quoted. When a quoted reference forms part of a larger type (e.g. Optional["MyClass"]), the wrapper persists in the formatted annotation.

Return types are however correctly parsed in either style.

Example

from typing import Optional

def all_quoted(arg: "Optional[MyClass]") -> "Optional[MyClass]":
    pass

def min_quoted(arg: Optional["MyClass"]) -> Optional["MyClass"]:
    pass

This produces the following, with ForwardRef wrapping the argument to min_quoted but not its return type:

Functions

all_quoted(arg: Optional[MyClass]) ‑> Optional[MyClass]

min_quoted(arg: Optional[ForwardRef('MyClass')]) ‑> Optional[MyClass]
