Destabilized Tetryon Weapons with scatter volley use standard tetryon graphics/sound

As the title states Destabilized Tetryon Weapons when using Cannon Scatter Volley use both the Destabilized Tetryon AND standard tetryon art and sound at the same time.

I've reported this a few times but figure now it's worth a dedicated post here. Should be a simple fix as someone just didn't setup the weapons to work right with scatter volley. Rapid Fire seems fine to me.
