Subject: [PATCH] Silence a concurrency warning on Linux/Windows building an
 actor-isolated test.

We have one `@MainActor`, `async` test on a non-sendable `XCTestCase` subclass.
Not surprisingly, this doesn't work fantastically well. Move the test out of the
class to fix the resulting compiler diagnostic.
