Fixed advertisement/bid/handover order bug

Previously the order was as follows:
- Place bids
- Advertise
- Check bids/handover

This has the undesired effect of causing double communication during time steps when a handover takes place. The order is now more sensible:
- Advertise
- Place bids
- Check bids/handover

The checkConfidences() method has also been renamed to advertisedTrackedObjects() for clarity.
