StabilizerNode.stabilize() should update lastTracking as well to avoid an unnecessary incentive.
Current logic pays unnecessary incentives to track the pool.
trackPool() pays an incentive per trackingBackoff in order to ensure pool consistency.
And stabilize() tracks the pool as well and we dont need to pay an incentive unnecessarily in trackPool() if stabilize() was called recently.
For that, we can update lastTracking in stabilize().
Recommend updating lastTracking in stabilize().
