Fix PHP 8 error for Participant Change Selections
Steps to reproduce, with PHP 8:
- View Participant with price set registration
- Click Change Selections
Result: Network error, Type error logged in Drupal log
Seems like $code can be either null or []. Not sure if those are meaningfully different, but I thought safer to just leave the variable as is rather than setting it null.
