Description of changes:

  • bugfix: inertialess tracers are now integrated along the z-axis (regression introduced in February 2022)
  • bugfix: a runtime exception is now raised when using more than 1 MPI rank with inertialess tracers + LB GPU
    • with LB GPU, inertialess tracers are silently skipped on MPI ranks >= 2

Let the Euler integrator update the position along all coordinates,
not just the x- and y-axes. Adapt the test case to check all three
coordinates are properly integrated. This fixes the regression
introduced by 29cf77d.
The LB GPU method silently skips inertialess tracers on non-root
MPI ranks. Now an exception is raised.
