Bug 8361: Do not allow checkouts if no rules are defined

Bug 8361: Do not allow checkouts if no rules are defined

We should require a circulation rule to allow checkouts and reject them
if no rules are defined.

Test plan:
- Delete all issuing rules
- Check an item out
=> Without this patch the checkout is allowed
=> With this patch applied it is rejected
