tests/entrypoints/test_fix_command.py sets TF_HISTORY, which makes the
real _get_raw_command call get_all_executables() and memoize the
machine's actual PATH. TestGetValidHistoryWithoutCurrent then mocks
thefuck.utils.Path to plant a fake café binary, but gets the stale
memoized list, so the café history line is filtered out and the four
parametrized cases fail whenever the entrypoint tests ran first.
Use the existing no_memoize fixture, like the neighboring
executables tests already do.
