fix: delete .worldcli cache file if it exists before creating .worldc…

…li directory (#54)

Closes: WORLD-1020

## Overview
Previously the `.worldcli` file was used as a cache for the last logged
in time for posthog. This file was moved to
`.worldcli/last_logged_time`, so the setup function should remove it
before creating the `.worldcli` directory.

## Brief Changelog
- delete .worldcli cache file if it exists before creating .worldcli
directory

## Testing and Verifying
Manually tested & verified
