Make the low population auto-shuttle unrecallable

[Technature]

We had a round today where the captain recalled the "everyone is dead" auto-shuttle call so he could keep doing telescience. On LLJK2. He was stuck in the first part of the Biodome for half an hour. The round continued for another half an hour with us screaming in ahelp before an admin (I assume) called the shuttle again. Everyone was dead and the game ground to a halt, which is both miserable and not fun.

Oh shit, I think I was the captain for that round.

I had no idea it was an auto-shuttle call.

I support this so I don't accidentally ruin literally 80% of the server's fun.  Again.

I also blame literally everyone else on the outgoing team cause they all told me to recall the shuttle in the first place
