[1.20.1] Loot Fabricator keeps on using power after all predictions have been consumed

[MatthiasMann]

Using version 5.3.1

Steps:

1. Place a loot fabricator
2. Connect power to fill it's storage
3. disconnect power - nothing happens
4. put in a few predictions (I put in 3 skeleton ones)
5. when they are all used the machine keeps using power

[MatthiasMann]

Slight correction:

• after all predictions are used up the power usage seems to be 0
• after a few seconds it increases getting faster and faster until the buffer of the machine is empty

[MatthiasMann]

It wasn't the loot fabricator itself - the enderio conduits somehow can extract energy from the loot fabricator - turning the machine into a kind of battery?!?
If I disable extraction on the conduits this phenomenon stops.
