Crash ``tuple index out of range`` because of missing import

[UncleOwen]

Bug description

When parsing the following file:
(Note that I'm missing the import for hypothesis.strategies.composite)

# These are tests. Do we really need docstrings?
# pylint: disable=missing-docstring

from typing import (
    Callable,
)


class AError(Exception):
    pass


class BError(Exception):
    pass


class CError(Exception):
    pass


@composite
def error_class(draw: Callable) -> BaseException:
    return draw(sampled_from((AError, BError, CError)))

pylint crashed with a IndexError and with the following stacktrace:

Looks like the one @DanielNoord fixed in #5549 as part of the Pylint 2.13.0 milestone.

[UncleOwen]

Indeed, looks just like it. I just tried to reproduce with current master, and there's no crash.
