replace flags.TrackOverlay with flags.TrackOverlay.ActiveConfig

The method I retrieve the TrackOverlay attributes is no longer working since last week. This doTrackOverlay flag is always False, so all events were sent to the MC-overlay in the hybrid approach:

The replacement ensures that the configuration is correctly set for the Track overlay workflow, and leads to a more reasonable CPU usage.

(13% of events were sent to track overlay here. Higher mu is more populated in the events I ran This percentage can increase with more events being run.)
