[9035] Attempt make more fast and less hackish spell target checks

* Enable server side recheck clear negative to friend or positive to enemy casts that already checks at client side
* Use more fast way check in similar cases for non-players, and fall back to old way in unclear (for while at least)

Please report if some spell stop propertly casted at friends/enemies.</pre>
