[0.15.30] Red/green circuit wires not consumed by bots

[jackd23]

I did a quick search and didn't find anything related to it, and I'm not sure if it's considered "not a bug", because this is also in 0.14.23 vanilla.

When building from a blueprint, construction robots don't consume any green or red wire to set up circuit connections. So the circuit wires magically pop into existence out of nowhere.

NaB, intended mechanic. They are also not listed in the ingredients of the blueprint, which is also intended. Kinda balances out that you don't get wires back when mining entities.
