Attempt to unbork CI

[stephanie-eng]

Description

This lovely set of tests appears to be causing some issues in CI.

Rather than doing init and shutdown for each test, let's init once and shutdown once. I'm not a wizard enough to understand why this suddenly started failing, but I think it's a good idea to init and shutdown like the other tests do.

Hoping this will fix CI failures in #3628 #3620 #3635 #3636 #3626 #3631
