Bug 15667: Fix date and branch formatting of messages in patron account display

This patch fixes the date and branch formatting of messages in patron
account display.

To verify:
Add a new message to a patron account from the 'checkouts' tab in staff,
the displayed date is not correctly formatted and the branch displays as code
instead as branch name

To test:
Apply patch, verify that the messages and branch names are properly formatted.
