Last bar not calculated in ChartDataSet.calcMinMaxY

Set a simple BarChartView like BarChartTests.
let values = [8, 104, 1000]
chart.autoScaleMinMaxEnabled = true

If set autoScaleMinMaxEnabled = false, then everything ok.

Start with ChartDataSet.calcMinMaxY and reproduce the report using a simple BarChartView like BarChartTests, with values [8, 104, 1000]. Compare autoScaleMinMaxEnabled set to true and false; done means the last bar is included in the calculated min/max range when autoscaling is enabled.
