note makes voiceOne go stems down

I don't think the problem with Phil's example is issue 34.  The point is  
that graceSettings aren't iterated, they're applied instantly at the start  
of a timestep in the Grace_engraver.  Before this engraver was added, this  
worked fine since all the set/unset processing was carried out via  
applyContext inside start(|stop)GraceMusic.  Obviously \oneVoice sends a  
load of stream events which arrive later than the start of translation, so  
the stem direction override ends up being reverted.
