[7414] Fixed premature finish timer messages for battleground (va_start was broken). Author: Triply

Fixed typo with BattleGroundPlayerMap.
    Optimized implementation for removing offline players from battleground.
    Fixed typo in BattleGroundMgr::DeleteAllBattleGrounds.
    Patch is tested and should work.

    TODO there is a bug if you disable premature finish timer, that can cause battlegrounds to be never ending!
    TODO rewrite BattleGround::RemovePlayer function - and fix bugs there!
    I might not have today enough time to fix those bugs.
