[Death Knight]: Control Undead works, but the pet doesn't attack

Bug description: After the fix to Control Undead, I went inside BRH and tried it out for myself. I could control mobs as intended, however they didn't attack properly. As seen in the example image below, my Risen Archer which is a ranged mob that's supposed to cast Shoot and Arrow Barrage, simply stood still far from the mobs with a "fist" animation. When trying different mobs, none seemed to cast or fully utilize their kit; some didn't attack at all. In retail, BRH mobs would cast their respective skills (Archers would cast Arrow Barrage if controlled, Soul-Torn Champions would cast Bonebreaking Strike and most importantly Risen Lancers would cast Raven Dive).
