[CLC-2388] Fake h2 entry for wait listed data on class in future semester

JIRA: https://jira.media.berkeley.edu/jira/browse/CLC-2388

@christianv see if this has what you need. It's stubbed out from MyAcademics::Semesters.new("300939") forward. Assuming that's the fake user you're pulling, the fake backend feed should return you a Spring 2015 Biology course that you're waitlisted 42/5000 in.
