Bug 26301: Use CanBookBeRenewed when renewing via self-checkout

Currently, if you have OverduesBlockCirc set to "Ask for confirmation"
and OverduesBlockRenewing set to "allow renewing", you get caught
in a loop where you can never renew an overdue material.

This patch uses CanBookBeRenewed for renewals, rather than CanBookBeIssued,
which means the correct rules are applied to the correct scenario.

To test:

a. Set OverduesBlockCirc to "Ask for confirmation"
b. Ensure "OverduesBlockRenewing" set to "allow renewing"
