Fix "instant respawning" when dying to trigger_hurt

[jensewe]

Clip where one of the teammate got a boomer as soon as Alyce died as boomer:
【RBT VII 瑞士轮 R7 - amagami [CN] vs r4w [SA]】 【精准空降到 10:11】 https://www.bilibili.com/video/BV1ZhWNe8EYX/?share_source=copy_web&vd_source=f80ca4a66aa762100701677bc8a0c4a8&t=611

Call chain:

1. CTerrorPlayer::MaterializeFromGhost
2. CBaseEntity::PhysicsRemoveTouchedList
3. CBaseEntity::PhysicsNotifyOtherOfUntouch
4. CBaseEntity::PhysicsRemoveToucher
5. CTriggerHurt::EndTouch

void CTriggerHurt::EndTouch( CBaseEntity *pOther )
{
	if (PassesTriggerFilters(pOther))
	{
		EHANDLE hOther;
		hOther = pOther;

		// if this guy has never taken damage, hurt him now
		if ( !m_hurtEntities.HasElement( hOther ) )
		{
			HurtEntity( pOther, m_flDamage * 0.5 );
		}
	}
	BaseClass::EndTouch( pOther );
}
