Fix the segmentation fault in the CKF by limiting the minimum track momentum during reconstruction. An excessively large qop value can lead the stepper to issue invalid track parameters (containing nan) during evaluate_dqopds and evaluate_dtds leading to a crash of the navigator.
TODO: Another source of such a track state seems to be from the Kalman Fitter in single precision with covariance inflation. Double precision seems to be fine, as is setting the inflation factor to 1 in single precision. Running in a debug build triggers an exception in the material_interactor that qop is zero. The source of this will need to be followed up (see also #944 )
