Rm13 armor can be activated for a few seconds even if no plutonium fuel is present

Describe the bug

As tiltle. This oddity can actually be expoilted in fight by spamming the activate button when armor goes off to keep almost 100% uptime or you can get few seconds of precious nightvision.
It should have that json thing that makes phase immersion suit requiering at least one charge loaded to try to start up armor's systems.
