Bug 31145: Supply defaults for vendors and funds

This is a convenience bug - when koha testing docker creates sample vendors and budgets there are small issues:

1 - The vendor website gets a random string - you can't edit the vendor without removing this
2 - The funds have random values for statistical categories, and you get empty dropdowns when choosing a fund in ordering

To test:
1 - Apply patch
2 - Restart all
3 - Edit 'My vendor'
4 - note webstie is empty and you can save without changing anythign
5 - Add order to basket for my vendor
6 - Confirm that when selecting a fund statistic 1 and statistic 2 remain as text input fields
