      It is technically possible for a user to manually create a "system.resharding." collection that isn't sharded. The invariants in ReshardingOpObserver::onInserts() and ReshardingOpObserver::onUpdate() should be changed to a uassert(ErrorCodes::NamespaceNotSharded, ..., metadata && metadata->isSharded()) to avoid crashing the server in such a situation.
