this transaction is not necessary. the final step of diff update is to save the metadata for the diff (branch, from time, to time, etc.) and this acts as a final stamp indicating that the diff is complete. if the diff update fails for some reason, there will be some unused nodes left behind in the database, but they will be ignored b/c the
DiffRoot
nodes will not have any of the metadata that we use to query for them.
