@Mastercuber the justification for simply disabling the tests is that
the entire implemntation for the follow activities is wrong. It's still
using the `AddUserFollowedBy` auto-generated mutation. The mutation that
is actually used when you do a follow or unfollow are called `follow`
and `unfollow` - these are custom mutations implemented by ourselves.
So the proper fix for these tests would be to refactor the entire
ActivityPub implementation. Since there is a pending PR already I
decided not to go down the rabbit hole and simply tag the failing
sceario as "work-in-progress" (@wip).
