tv slave and "ETL DEMO STATS BOT" conflict crash

if sv_etltv_maxslaves==1and sv_autodemo 1 then connecting tv slave conflicts with "ETL DEMO STATS BOT" and eventually crashes server later

setup: etlded +set fs_homepath ... +map oasis +sv_etltv_password 3ttv +set sv_autodemo 1 +sv_etltv_maxslaves 1 +g_warmup 10 then right after run: etlded +set fs_homepath ... +tv connect localhost:27960 3ttv +wait 1000 +echo quitting +quit

tv slave will cause "ETL DEMO STATS BOT" to drop and when warmup countdown finishes and server tries to re-add "ETL DEMO STATS BOT", it SIGSEGVs at:
