[1.1.110] Bots persist to next round in team production

[thedoh]

If you have bots flying in the air before the round ends, they will still be in the air for you (or someone) to claim in the next round. It seems like the cleanup script neglects to pluck bots out of the air. No log file since I wasn't the host, but it should be easy enough to reproduce.

Thanks for the report. Issue is now fixed for 2.1.

It looks like most of entities were cleared due to tiles being changed to out-of-map, but this was not affecting flying robots. For a fix i made clearing also look for entities and remove them.
