Code Issues Proposed changes

Only send one newchange email from PostReviewer

Browse Source 
The PostReview REST endpoint translates each new reviewer in the request
into invocations of the PostReviewers REST endpoint, which would send a
newchange email each time a reviewer is successfully added. Because the
PostReview endpoint allows several Reviewers and CC'd users in batch,
prevent the PostReviewers sub-calls from sending emails, and send one
newchange email at the end.

Tests are updated to reflect fewer emails being sent and to reflect CC'd
user names no-longer appearing in the email salutation.
