Crash in PlayerDeathSystem while trying to update statistics

[skaldarnar]

During play-testing https://github.com/MovingBlocks/Terasology/releases/tag/v5.2.0-rc.1 the (headless) server crashed due to the following NPE when updating the player statistics:

java.lang.NullPointerException: null
        at org.terasology.ligthandshadow.componentsystem.controllers.PlayerDeathSystem.updateStatistics(PlayerDeathSystem.java:93)
        at org.terasology.ligthandshadow.componentsystem.controllers.PlayerDeathSystem.beforeDestroy(PlayerDeathSystem.java:63)
        at org.terasology.ligthandshadow.componentsystem.controllers.PlayerDeathSystemMethodAccess.invoke(Unknown Source)
        at org.terasology.engine.entitySystem.event.internal.EventSystemImpl$ByteCodeEventHandlerInfo.invoke(EventSystemImpl.java:379)
        at org.terasology.engine.entitySystem.event.internal.EventSystemImpl.sendConsumableEvent(EventSystemImpl.java:254)
        at org.terasology.engine.entitySystem.event.internal.EventSystemImpl.send(EventSystemImpl.java:233)
        at org.terasology.engine.core.bootstrap.eventSystem.AbstractEventSystemDecorator.send(AbstractEventSystemDecorator.java:67

This occurs when the player does not have a PlayerStatisticsComponent.

Lines 90 to 99 in 8c937cd

	private void updateStatistics(EntityRef player, String type) {
	PlayerStatisticsComponent playerStatisticsComponent = player.getComponent(PlayerStatisticsComponent.class);
	if (type.equals("kills")) {
	playerStatisticsComponent.kills += 1;
	}
	if (type.equals("deaths")) {
	playerStatisticsComponent.deaths += 1;
	}
	player.saveComponent(playerStatisticsComponent);
	}
