Extract only exact scores to get the PV

This should allow to skip overwritten nodes because
only in PV we store in TT with VALUE_TYPE_EXACT flag.

Test result for the whole series is:

After 3627 games at 5"
Mod vs Orig +1037 =1605 -985 +5 ELO

After 1311 games at 1'+0"
Mod vs Orig +234 =850 -227 +2 ELO
