[Bug] startdemo command broken

[Alerymin]

Compared to original engine, demo does not play when the game starts, but the text "3 demo(s) in loop is showed".

From what I found, it's generated by the console command startdemos demo1 demo2 demo3. When entering this command, the game should play all 3 demos, but it doesn't.

So is it the reason why demos are not played automatically ?
