[FIX] pos_online_payment_self_order: remove unnecessary test flag from tour

In this commit:
- Removed the `test: true` flag from the `test_kiosk_cart_restore_and_cancel`
tour.
- The flag is not required for tours and can cause issues when running in
debug mode.
- This issue only occurs in local environments when debug mode is enabled.
- After this fix, no issue is generated in debug mode.
