Tests have started to output too much log content, causing viewing CI
failures to be painfully impossible. Roll back for now.
Fix may be related to
https://github.com/nunit/nunit3-vs-adapter/issues/941, although we don't
use filter.
This came up while testing the new realm thread, where `MusicController`
would fall over when `OsuTestScene` changes the global beatmap from an
async load thread (causing a cross-thread realm access).
We don't want to have to schedule every usage of these bindables, so
this seems like a good constraint to put in place.
I can't confirm this works yet, since I'm not sure what the
preconditions are for the `.note` file to be created. What I can confirm
is that a `.note` file hasn't appeared in my game data directory yet.
