Update session state checks for contest information in app.py

- Modified the condition for checking the presence of 'display_contest_info' in session state to enhance data handling and prevent errors.
- Added a safeguard to stop execution if 'display_contest_info' is not available, improving application stability and user experience.
- Ensured that player columns are only processed when relevant contest data is present, maintaining data integrity.
