Bug: Illidari Council

### Current Behaviour

The trigger NPC (ID: 23426) doesn't receive the whole damage inflicted.

example:
if i deal ~3.3k damage with Damage5 (GM spell), the trigger does receive way less (i guess it's because of damage-modifier by autobalance)

this causes the bosses to heal back up to nearly 100% everytime "spell_illidari_council_empyreal_equivalency" (Spell ID: 41333)(boss_illidari_council.cpp) gets executed.
making the boss practically not soloable.

i think it's because autobalance interferes with the damage "spell_illidari_council_empyreal_balance" (Spell ID: 41499) transfers to the trigger? (or at least i assume that's the function that does that)

### Expected Behaviour

Trigger should receive all the damage inflicted to the bosses.
(max hp of trigger is correct)

### Steps to reproduce the problem

1) Solo Black Temple
2) Deal damage
3) Boss(es) gets back up to ~100% all the time.

if you test with two accounts (boss fighting account and one in gm mode) you can see the trigger in the back off the room with the gm account.

see .server debug

Read boss_illidari_council.cpp and trace spells 41499 and 41333 alongside the mod-autobalance behavior. Reproduce the solo Black Temple case and compare damage reaching the bosses and trigger NPC 23426. Done means the trigger receives all inflicted damage and the bosses no longer heal back to nearly 100%.
