Before this patch, and after transaction support had been added #24258, if the server had not removed old parts on shutdown, then they will left forever. Fixes: #24258 (cc @tavplubix) v2: use Tx::PrehistoricTID over removePartsFromWorkingSet() from ctor v3: apply black to new test Signed-off-by: Azat Khuzhin <a.khuzhin@semrush.com>
