Bug 23296: Set patron branchcode when preparing non-digest version

To test:
1. APPLY PATCH
2. Set up circ rules to allow for auto renewals.
3. Set AutoRenewalNotices to 'according to message prefs'
4. Make a branch specific version of the the AUTO_RENEWAL notice.
5. Find a patron belonging to that branch and set the message prefs to allow for a AUTO_RENEWAL. But no digest option!
6. Check some things out and make sure they are eligble for auto renewal.
7. Run the cron.
8. Make sure the patron gets the branch specific notice.
9. Delete the branch specific notice.
10. DO 6-7 again.
11. Make sure they now get the all library notice.
