Merge pull request #702 in VECTO/vecto-sim from ~EMQUARIMA/vecto-sim:bugfix/VECTO-696_regression to develop

* commit '90e859f3':
  correct testcase: expected torque loss is 0 in case the angular speed is 0
  Gearbox: set torque loss to 0 if angular speed is 0. already done for transmission component and gearbox when disengaged. added for engaged gear.
