Run SyncExpectation's expression in async contexts of toEventually on the main actor. #1044

This PR prevents a main thread checker error.

Basically, the following test would actually fail prior to this PR:

@MainActor
func test_example() async {
    await expect(Thread.isMainThread).toEventually(beTrue())
}

which, if you replace the Thread.isMainThread part, with, say, checking a UIKit API, could cause a test crash due to the main thread checker causing crashes when run in debug mode.
