cgoldfeder 0267214841 Replace some unnecessary uses of "real" ofy() with Ofy.
Only Ofy itself and its two helpers (AugmentedSaver and
AugmentedDeleter) need to use the real ofy(). All other
callers should be using Ofy. Fixing this even though it
doesn't change anything because I found it baffling to
follow the code while trying to make a small change.

Update: added a presubmit to enforce this.
