Fix out of order event errors on save with overlapping notes.

Another consequence of fuzzy Sequence timing, but if the difference is less
than a tick this should handle things correctly.  If the difference is more
than a tick, something's wrong, and it might be okay to just bump forward
anyway, but I can't reproduce this and it could lead to corruption so I'm
leaving that case noisy.
