It should be after that test. But its purpose is to check what happens later
when you revert the course reserve and put back the original value..

Yes it is. Your example below is the proof ! NULL vs empty string

> $item->ccode(undef)->store;
> MariaDB [koha]> select ccode from items where itemnumber = xxxx;
