Attempt to fix chest minecarts, at least for 5.9 (#4684)

Browse source 
Not using the `RecheckCartHack` on >5.9 seems to help with #4670 - not tested on older minetest; chest minecarts might still be empty there when the block is unloaded in the meantime. For <5.9, maybe it helps to decrease the time interval, 3 seconds seems to fairly long.

This also makes the minecarts random: 40% minecart, 40% chest minecart, 20% tnt minecart.
