Fix validation particles flickering in certain situations

In a multi-structure pack, if another structure had an empty layer (i.e. no blocks to validate), being on validation mode on that layer but with another structure would cause the animation controller state to go back and forth.
Also fixed content log issue regarding v.hologram_dir being undefined in punch-to-activate mode.
