Description

Hi I've tried lots of things but I cannot get the treeview aggregations to recalculate when new data is spliced into the data.

Plunkr: http://embed.plnkr.co/EChR0W1QHUvCc5dilHV4/

I have managed to force it by deleting the '$$uiGrid-x' properties from the objects with $$treelevel defined but this seems a little brutal.

Research direction
Investigate the provided Plunkr (http://embed.plnkr.co/EChR0W1QHUvCc5dilHV4/) to understand the splice operation and treeview aggregation update mechanism. Look at the ui grid source code for how aggregations are recalculated when data changes, particularly the handling of $$treelevel and $$uiGrid x properties. The issue may require resetting those internal properties or modifying the change detection logic.
