Do not cd in the chpwd hook

This is not really necessary, except for the convenience of being in the
.env file's directory during the hook.
But it messes around with the "cd history", e.g. `cd -`!

To reference the .env file or its directory, `$autoenv_env_file` and
`${autoenv_env_file:h}` can be used instead.
