Title: Add admins to email

http://manage.dimagi.com/default.asp?128491

Found that trial ending subscriptions were not being sent.

Changed emails to a set in case an email is both a project admin and billing admin.

@nickpell

@biyeun should we have title case for the subject or anything else here?
