Same as ac920d1f, except this time for vtkChartParallelCoordinates. The fix exposed a problem with vtkPlotParallelCoordinates where when the selection was set to NULL, it was never updated after that. This was incorrect (since for a similar condition in vtkPlotPoints, we create a new vtkIdTypeArray, when none is present). Fixed that following the pattern in vtkPlotPoints.
