Initially, I tried to write a test for a race condition between StorageReplicatedMergeTree::updateQuorum and StorageReplicatedMergeTree::cleanLastPartNode: https://gist.github.com/tavplubix/b2c5d98c0995ff9e986ca6f95827d190

However, this race condition is quite rare and not harmful, nobody cares about it, and a fix would require a backward incompatible change... So it's easier to keep it as is.
