Correctly set mateThreat in search()
We do not accept null search returned mate values,
but we always do a full search in those cases.
So the variable mateThreat that is set only if null move
search returns a mate value is always false.
Restore the functionality of mateThreat moving the
assignement where it can be triggered.
