MovePicker: fix a nasty bug in EvalInfo optimization

EvalInfo has missing attack info when a specialized
endgame function is used.

We missed this case and were using an empty attack bitboard
instead so that no captures were generated for endgames.

After testing the EvalInfo optimization gave worst results,
so after a (long) debug session this nasty bug was found.
