Vengeful Ghost skill damages tamed beefalo and causes domestication loss

Vengeful Ghosts have no auratestfn defined, unlike Abigail who has a very comprehensive one that excludes companions:

-- prefabs/abigail.lua, line 274
local function auratest(inst, target, can_initiate)
-- ... line 316
    return not target:HasTag("companion") and
        (can_initiate or ismonster or target:HasTag("prey"))
end

This results in various friendly targets getting damaged, but most notably applies a very punishing 30% domestication loss for every hit to beefalo. The skill is avoided like the plague in public servers, as anyone dying within the skill's radius automatically transforms into a beefalo untaming machine.
