scheduler: goroutine ssntp Stop() in test case

The tests propagate event results through channels.  Writers to channels
block until a reader reads.  The reader of a node disconnect event result
doesn't start to read untils the reader code (after the server stop call)
actually runs, which it wont do if the server stop is not a go routine.  If
the stop code is blocked on sending to the channel and the reader only runs
when the stop code is complete (ie: because it is not stopping in a
goroutine) there's going to be a deadlock.
