Anode/Cathode on battery appears reversed

I think the anode/cathode on the battery (i.e. source) might be reversed. Here's a log showing that, for the electrical circuit task, a circuit connected as such doesn't work:

- Battery anode -> wire -> light anode
- Battery cathode -> wire -> light cathode

But the reverse does appear to work (e.g. anode->cathode instead of anode->anode).

The anode/cathode chaining is required for loads (like the LEDs), but not for the sources (e.g. the battery). Should:
- Check the simulator and fix this bug
- Fix any issues w/gold agents and regenerate training data for these tasks
