fix: correct rate limiting calculation to prevent incorrect delay display

- Fixed rate limiting logic in Task.ts to properly handle undefined lastGlobalApiRequestTime
- Added check for rateLimit > 0 before applying rate limiting
- Simplified calculation to only apply delay when there's actually time remaining
- This prevents the incorrect '15903 seconds' message reported in issue #7770
