Call of Chernobyl 1.4.22: NPC sound play crash

[Nullpoint56]

Describe the bug
A crash happens to the bug reporting screen randomly. I suspect it is related to NPCs playing music instruments or speaking.

To Reproduce
Steps to reproduce the behavior:

1. Start a new game with population factor as high as possible (so you won't wait for eternity to it to happen)
2. Go to a campfire or stand in one place (couldn't see a difference)
3. Wait for the bug to happen.

A quick and dirty way to avoid crashing (not solve it). I edited sound_theme.script at npc_sound:play() function to check if played_id is not a nill before doing anything with it.

Correct fix for the script file is this:
