Don't fail on account update if the user branch is missing

If the account does not exist AccountsUpdate#update should return null
and the provided consumer to update the account should not be invoked
(if it's invoked with a null account the consumer likely fails with a
NullPointerException).

If the account only exists in ReviewDb the missing user branch should be
created.

At Google we run into this problem because we haven't migrated all of
our accounts to NoteDb yet and hence for a few accounts the user branch
is still missing.
