Acts TrackFinding: fix index out of bounds with useCache
Compare changes
TrackFindingMeasurements::addMeasurements now uses a simple index counter instead of measurement->index() when creating MeasurementRangeList. index() gives the index into the owning collection, whereas we want the index into the input collection. These will be different if the input collection is a view.

If either had been set False, there would have been a mismatch in HandleKeyArray sizes.
