Addition of type annotation breaks tab completion in jedi>=0.19.0

[daveah]

Start with this code in ipython with jedi enabled for tab completion:

from typing import Iterable, Any

class Bar:
    def __dir__(self) -> Iterable[str]:
        return ("a", "b", "c")
    
    def __getattr__(self, key: str) -> Any:
        if key not in ("a", "b", "c"):
            raise AttributeError
        return self[key]
    
    def __getitem__(self, key: str) -> "Bar":
        return Bar()
    

class Foo:
    _b: Bar | None

    def __init__(self) -> None:
        self._b = None

    @property
    def b(self):
        if not self._b:
            self._b = Bar()
        return self._b

f = Foo()
f.b.   <hit tab>

We get what we expect with a menu of a, b, c in jedi 0.18.1 or 0.19.0 and later

Now add a type annotation to the @property in Foo:

from typing import Iterable, Any

class Bar:
    def __dir__(self) -> Iterable[str]:
        return ("a", "b", "c")
    
    def __getattr__(self, key: str) -> Any:
        if key not in ("a", "b", "c"):
            raise AttributeError
        return self[key]
    
    def __getitem__(self, key: str) -> "Bar":
        return Bar()
    

class Foo:
    _b: Bar | None

    def __init__(self) -> None:
        self._b = None

    @property
    def b(self) -> Bar:
        if not self._b:
            self._b = Bar()
        return self._b

f = Foo()
f.b.   <hit tab>

This now works in 0.18.2 but fails in 0.19.0 and above.
