Interestingly this patch will make people complain search depth is reduced against 2.0.1 ;-) but actually it is only an artifact. Spotted by Joona. No functional change apart from a different do / undo move sequence due to teh fact that we don't call pv_info_to_uci() anymore before entering id loop.
