Issue
When using a light connector hooked up to a relay to turn it on an off, the lights will not turn on unless there is a load on that line.

To Reproduce
Hook up a power source to a relay, then connect the relay to the string of light connectors. When the relay is flipped on, the lights will not work. But if you hook up a motor, accumulator, etc... to the end of the lights it will turn them on.

Additional context

• Mod version: Minecraft 1.20.1
• Forge version: 47.2.0
• Create version: Crafts and Additions 1.2.3

This has been fixed

I think that network.demand must be called somewhere in the specialTick method of SmallLightConnectorBlockEntity
