Increase reduction in case of stable best move

The idea of this patch is pretty simple - we already do more reductions for non-PV and root nodes in case of stable best move for depth > 10. This patch makes us do so if root depth if > 10 instead, which is logical since best move changes (thus instability of it) is counted at root, so it makes a lot of sense to use depth of the root.
