labelMoment is undefined

[jhiemer]

Hi,
perhaps this is a stupid question, but using Chart.js with Moment and multiple Series, I sometimes do get labelMoment is undefined, which can easily be fixed via:

    getPixelForValue: function(value, index, datasetIndex, includeOffset) {
            var labelMoment = this.getLabelMoment(datasetIndex, index);
      if (labelMoment) {

in line https://github.com/nnnick/Chart.js/blob/v2.0-dev/src/scales/scale.time.js#L269.

What do you think?
