Event product list: Fix another performance issue for large series

This is a follow-up for #6318, basically the same problem but in a
neighboring query.

Performance comparison for real-world event with 13k subevents:

In [15]: %time get_grouped_items(e, subevent=se, channel=e.organizer.sales_channels.get(identifier="web"))
CPU times: user 49.1 ms, sys: 3.79 ms, total: 52.9 ms
Wall time: 1.12 s
Out[15]: ([<Item: xxx>], True

In [16]: %time get_grouped_items_patched(e, subevent=se, channel=e.organizer.sales_channels.get(identifier="web"))
CPU times: user 30.2 ms, sys: 445 μs, total: 30.6 ms
Wall time: 45.3 ms
Out[16]: ([<Item: xxx>], True)
