BB-547 - Fix certificate api when retrieving certificates from deleted courses

This commit fixes a problem with the Certificates API that make it fail when trying to retrieve user certificates from courses that don't exist anymore.
The problem lies in the Certificate API not checking if the courses being retrieved by some user actually exist, to fix this, this commit improves the fault tolerance of the Certificates API.

This issue was found when investigating why a user profile page (/u/username) was returning 404's.
Turns out that LearnerAchievementsFragmentView used the certificates api to retrieve certificate information, which did not check if the course exists before trying to pull information from it, resulting in a cascade of errors that lead to a 404 on the user's profile page.

In order to add the functionality of sending email when verification expires we need to add fields that will help in accomplishing the task

The fields added are:

expiry_date : The date when the verification will expire. updated when the sspv verification is apporved
expiry_email_date : The date when email was sent. This will help filter learners so that we don't send email again and again but only after specified time
