Core/Spells: Fix a small proc-issue with hunter T10 set bonuses (Exploit Weakness)

(original fix by Dr.Tenma)
Comment issue #4362
From DBCs TargetA[0] is already set as TARGET_UNIT_PARTY_CASTER, which maps to TARGET_UNIT_CASTER,
so it should be enough to explicitly target the casters pet in this case, ie. just doing
spellInfo->EffectImplicitTargetB[0] = TARGET_UNIT_PET; - feedback on this required.
