Review Comment:
Apologies, you're right. I still think does can create duplicates.
I think maybe we should extend `TopicDelta.localChanges` to also consider
changes to the assigned directory to replicas hosted in the broker. Then we can
gate calling `maybeUpdateTopicAssignment` unless `localChanges.directoryIds` is
empty.
