Don't auto-approve changes when they are uploaded

The entire point of the code review systems is to have another
party beyond the uploader review the changes to determine they
are suitable for inclusion, and set the approval bits onto the
change record.  Automatically approving your own changes reduces
the value of this 3rd party review.
