Is this function call still needed?

I'm really not sure if it is or not. I thought it would be safest to keep it and see what people think. @tniessen Do you by any chance know if this function call is needed?

@danbev That function should not have side effects, so it should be safe to remove the function call. I am not really sure how new vm.Script honors displayErrors despite not using that option 😕

Maybe it's time we turn on -Werror for files in src/, at least for developer builds...

@danbev Can you note in the commit log that this was introduced in #17394 / aeddc36? Might be useful knowledge if it turns out it breaks something.

@MylesBorins This commit depends on aeddc36 ("src: remove tracking for exception arrow data") PR: #17394, and should not break if that commit is applied first.
