LP#1887876 Checkout catalog doesn't load workstation prefs

The catalog under the Holds tab in the Checkout interface
doesn't load the default search or preferred library if
you haven't visited the main catalog page earlier in the
session.

This branch sets these settings as cookies in the
AngularJS wrapper for the catalog embedded in the Checkout
interface under the Holds tab.

Test:
1. Close browser, open browser, log into Evergreen
2. Admin->Workstation set search & preferred library
3. Open a patron record -> Holds tab -> Place Holds
4. Search for an item owned by your preferred library
5. Note the library's copies aren't separately indicated
6. Apply patch and repeat steps 1-5
7. Note the library's copies are separately indicated
