Description
In certain cancellation scenarios, the InitialSyncer will be canceled with a retryableOperation still active. If this operation is active when the InitialSyncer is destroyed, it will access an already-destroyed InitialSyncSharedData. So we must destroy it in _finalCallback
This was found in BACKPORT-7799 and so does not need to be backported to 4.4.
