Fix an off-by-one bug in extract_pv_from_tt At root we start counting plies from 1, instead pv[] array starts from 0. So the variable 'ply' we use in extract_pv_from_tt to index pv[] is misnamed, indeed it is not the real ply, but ply-1. The fix is to leave ply name in extract_pv_from_tt but assign it the correct start value and consequentely change all the references to pv[]. Instead in insert_pv_in_tt it's simpler to rename the misnamed 'ply' in 'idx'. The off-by-one bug was unhidden when trying to use 'ply' for what it should have been, for instance in this position: position fen 8/6R1/8/3k4/8/8/8/2K5 w - - 0 1 at depth 24 mate line is erroneusly truncated due to value_from_tt() using the wrong ply.
