Use full ICE history for displaying estimated carbohydrate effects (#2163)

The 'predicted' dataset on the 'glucose change' graph was calculated using insulin counteraction effects that had been truncated to the width of the chart. This meant that carb entries early in the timeline may not have dynamic carb absorption applied as the implied ICE was zero for the first part of the carb entry's history.
