Hits from a planar entity can only show the planar hit fx if the target has an inventory component

This is due to this bit of code being encased like this, in Combat:GetAttacked:

if self.inst.components.inventory ~= nil then
	if attacker ~= nil and attacker.components.planarentity ~= nil and not self.inst.components.inventory:EquipHasSpDefenseForType("planar") then
		attacker.components.planarentity:OnPlanarAttackUndefended(self.inst)
	end
	damage, spdamage = self.inst.components.inventory:ApplyDamage(damage, attacker, weapon, spdamage)
end

OnPlanarAttackUndefended should still be called on entities without an inventory component, as that means they can't have planar defense (maybe check that the target isn't also a planar entity, which is also missing in the current iteration of the code).
