User RaceFreeFakeWatcher isntead of FakeWatcher in TestAddRemoveNode
function. The test runs c.Start() in a goroutine whch stops the watcher
when done. If mockNodeOrchestrationCompeltion sends a watch ever after,
that, FakeWatcher panics with "send on a closed channel".
RaceFreeFakeWatcher safely ignores the sends on a stopped channel.
