Bug: Superset first sign-in hangs on instructor dashboard

[bmtcril]

When a user (instructor or admin) first signs into Superset then clicks into the Instructor Dashboard, the charts all spin and the filters don't populate. They appear after a refresh. I assume this is a timing issue that has to do with getting permissions from LMS, but we should look into fixing it if we can.

BTW, I did find that if you click the filters suddenly the dashboard load

Apparently this is fixed in Superset 2.1.0: apache/superset#23299
Do we know of anything preventing us from upgrading to 2.1.0?

Conversely, we could drop the requirement for a problem or video name to be selected for those component-level tabs.

I think @Ian2012 looked into 2.1, but we're also very close to a 3.0.0 which might be worth just biting the bullet and jumping to if it's not terrible. I can create a task to investigate once Apache approves a 3.0 RC, which should be any time now.
