fix a bug that lead to segfault when MHD+Fargo+MPI (with X3 domain decomposition) are all enabled, and the azimuthal shift performed by fargo is larger than one cell.
This went undetected for a while as the test FargoMHDSpherical was actually testing for small fargo shifts (less than a cell). The new version of the test validate the code up to 2 cells in shift.
