Direct Linking to User Record Now Leaves Empty Middle Pane

Steps to repro:

1. Log into snapshot-stable
2. Go to Checkout App
3. Click Patron lookup
4. Choose a user in the Patron lookup modal
5. Click on the patron name or barcode under the Borrower section to view full user details

Actual: User details is displayed in far right pane but there the is big empty middle pane now (this is the result of no longer displaying all users by default)

Expected: The middle pane should display the result clicked. See attachment UIU_441_bug.
