Unlit redstone torches use the redstone torch template model, rather than the torch template model

Discovered while testing MC-275792.

The bug

The unlit redstone torch points to the template model used by the lit redstone torch.

This results in no visual difference in-game (besides MC-275750), however it results in the inside-out cube glow effect being rendered but with an invisible pixel. As a result, large amounts of unpowered redstone torches will render twelve extra triangles that they don't need to, which can cause a lot of avoidable rendering lag.

How to fix

Repoint redstone_torch_off.json and redstone_wall_torch_off.json to use the normal torch template model.
