[1.18.2] NPE in PowerEventHandler.onBoneMeal() if bonemeal is used by dispenser

[linuskr]

When bonemeal is used by anything not a player, event.getPlayer() returns null, and calling .getRandom() on that then crashes the server.

java.lang.NullPointerException: Cannot invoke "net.minecraft.world.entity.player.Player.m_21187_()" because the return value of "net.minecraftforge.event.entity.player.BonemealEvent.getPlayer()" is null
