fixes COMMS-1781
Test Plan
* Make sure to run bundle exec rake db:migrate
* Trigger the confirm_email_communication_channel or
confirm_registration event on the Communication Model
* We can do this by adding a comm channel in the console
going over to the channels and adding an email on the
account
* notice that when its added it will attempt to send
a confirmation
* We can look at rails c and notice that the new
confirmation_sent_count column will be incremented
