  [scudo][standalone] Lists fix

Summary:
Apparently during the review of D69265, and my flailing around with
git, a somewhat important line disappeared.

On top of that, there was no test exercising that code path, and
while writing the follow up patch I intended to write, some `CHECK`s
were failing.

Re-add the missing line, and add a test that fails without said line.
