Modify check_output to explicitly pass the errors object to is_valid_rij_list

Thanks! However, there's another call to is_valid_rij_list() in the function check_evals() that would also need to be changed.

In thinking about this more, it looks to me like errors is never really used within is_valid_rij_list(), so rather than passing it as an argument, I think we can just initialize errs <- c().

Yes, that makes sense to me!
