Disable eager-refinement step of region tracking
This gives much worse results on mango footage (see 04_2e)
so disabling for now for until proper prediction model is landed.
The thing is, currently blender sends input coordinates as the guess to
region tracker and in case of fast motion such an early out ruins the track.
