Battle Shout used from various tbc trash npcs should not stack

[miraco]

🍰 Pullrequest

Battle Shout should not be stackable.

Issues

Using Ethereal Crypt Raider as example here:
This npcs can use Battle Shout on their self. Pulling multiple npcs of this type can result in overstacking Battle Shout.

Tests on retail showed that they use it on their self even if they have the Buff (refreshing timer from 1min to 2 minutes)

I know that this code change works since grz3s tried to do similar, but this is not the actual fix. This just makes it incompatible cos a StackAmount check is done against other auras, and if they dont equal, they arent considered the same.

I will check what the current way of doing it is and update the PR.
