[BUG] Battle elixir removing Guardian elixir

[lavinelu]

For example, consuming the normal guardian elixir 'Elixir of Mighty Fortitude' (http://www.wowhead.com/item=40078) removes the battle elixir 'Elixir of Mighty Strength' (http://www.wowhead.com/item=40073) and vice-versa.

i think the problem is from this function IsNoStackAuraDueToAura and should be something like this

 if (spellInfo_1->Effect[i] == spellInfo_2->Effect[j]
               && spellInfo_1->EffectApplyAuraName[i] == spellInfo_2->EffectApplyAuraName[j]
               && spellInfo_1->EffectMiscValue[i] == spellInfo_2->EffectMiscValue[j]
               && spellInfo_1->EffectItemType[i] == spellInfo_2->EffectItemType[j]
               && (spellInfo_1->Effect[i] != 0 || spellInfo_1->EffectApplyAuraName[i] != 0 || 
                   spellInfo_1->EffectMiscValue[i] != 0 || spellInfo_1->EffectItemType[i] != 0))
               return true;

should be fixed in [10417]
