SF threshold in PMF is not relative #1582

When using the LocalTracking a ProbabilisticDirectionGetter needs to be provided, ProbabilisticDirectionGetter requires a relative_peak_threshold. Which is supposed to ensure that a linear scaling of FODf amplitude does not affect the tracking.

Same datasets, artificially scaled FODf (factor 0.1, 1, 10) should produced identical tracking. This is not the case. The results are that tracking using the factor 0.1 results in 0 streamlines and a large difference is observable between the local tracking using the factor 1 and the factor 10.
@gabknight is the sfthreshold aimed to cover this situation ?
