microbit-dal: patch for fiber_wake_on_event
fiber_wake_on_event used to crash after forking a FOB fiber.
It would attempt to obtain a new fiber context, and would place it on the wait queue.
Then when that fiber was paged in, the context of that fiber would not have been
initialised, as the function presumed schedule would be called immediately after
fiber initialisation.
This patch catches that edge case.
