Subject: [PATCH] parser.utils.clear_cache: clear self.__index
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This fixes a potential FileNotFoundError when clearing the cache
manually, using the method from
https://github.com/davidhalter/jedi-vim/pull/625.

Traceback:
