Bug 37983: Restore auto-focus on patron input when "Schedule a pickup" is selected

In the curbside pickup module, when the "Schedule a pickup" tab is selected we expect
the patron search box to get the focus. But it has been broken bug 30965 (which changed the id of the input).

Test plan:
Setup curbside pickup for your library
Go to Circulation > Curbside pickups
Click the last tab
Notice that you can directly search for a patron, the input has the
focus
