Correct cancellation and asyncio test prose

Fix five spelling errors in comments and failure text touched by the
one-shot migration: one `propagate`, one `Daemon` and three `directly`
corrections.

Review: PR #484 (GitHub Copilot)

+Remove legacy ``ActorNursery.run_in_actor()``,
+``Portal.wait_for_result()`` and ``Portal.result()``. Use
+``tractor.to_actor.run()`` for caller-owned one-shot tasks,
+``Portal.run()`` for daemon RPC results or ``Portal.open_context()``
+for linked task dialogs.
