Minimal thinking time, even if only one rootMove. without search, the eval returned can be misleading (e.g. mate instead of draw), leading to wrong adjudication. With a minimal search, this is avoided. This patch leads to 1ms long searches if there is only 1 move, similar patches all indicate a small Elo gain.
