Scripting/Howling Fjord: Fix Quest 11310 Warning: Some Assembly Required

Quest is doable and completeable with the following Issues:
Aura not being removed from player after Abomination explodes.
Camera angle should not changes after Abomination explodes.
Can't check if Abomination leaves Halgrind. GetAreaId returns players area id.
