Bug 41898: (QA follow-up) Only list uncollected bookings on the pending list

The pending bookings page lists items that have not been collected yet,
but the status filter added when the server-side active pre-filter was
removed included 'issued' bookings, so bookings reappeared on the list
after the item had been checked out.

- restrict the status filter to 'new'

Test plan:
1. Place a booking starting today and open Circulation > Bookings to
   collect; the booking is listed
2. Check the item out to the booking patron; reload the list and
   confirm the booking is gone
