Subject: [PATCH] [IMP] website_slides_survey: add survey course visibility

Previously there was no way to view when a survey (specifically a
certification survey) was being used by a course from the survey
app. We handle 2 cases for when a survey is currently assigned to
a course:

1. A survey is assigned to 1 course => survey form stat button visible to bring user
   directly to corresponding course form.
2. A survey is assigned to more than 1 course (unlikely, but currently possible) =>
   survey form stat button visible to show user a list of corresponding courses where
   each list entry can be clicked on to view corresponding course form.

Note: we do not cover viewing courses a survey was previously assigned to as this would
   be currently be unreasonable to track.
