Make staticEval independent of the search path
Current master can yield different staticEvals depending on the path used to reach the position. The reason for this is that the evaluation after a null move is always computed subtracting 2 * Eval::Tempo, while this is not the case for lazy or specialized evals. This patch always adds tempo to evals,
which doesn't affect playing strength:
LTC
LLR: 2.96 (-2.94,2.94) [-3.00,1.00]
Total: 59911 W: 7616 L: 7545 D: 44750
STC
LLR: 2.95 (-2.94,2.94) [-3.00,1.00]
Total: 104947 W: 18897 L: 18919 D: 67131
Fixes issue #1335
