refactor(clickTtPlayerRegistrationService): improve nationality selection logic

- Updated nationality selection to handle multiple selectors, enhancing flexibility in form filling.
- Added checks for 'WONoSelectionString' and specific values to improve validation during player registration.
- Streamlined the selection process by breaking out of the loop once a valid selection is made, improving efficiency.
