Title: Fix an error raised when some node data are empty.

Sometimes node data could be empty (for example, the application uses `gevent.spawn()` heavily, but I’m not sure why). In that case, several points of linesman raise `KeyError`.

It fixes node data to have `'totaltime'` key before graph data are used.
