Fix a minor bug in search As Joona says: "The problem is that when doing full window search (-VALUE_INFINITE, VALUE_INFINITE), and pruning all the moves will return fail low which is mate score, because only clause touching alpha is "mate distance pruning". So we are returning mate score although we are just pruning all the moves. In reality there probably is no mate in sight. Bug spotted and fixed by Joona.
