Fixed cell debugger problem with remote kernels (microsoft#11396)

  receives from the kernel based on the OS where VSCode is run, because
  it leads to files not being found on the kernel side, which in turn
  breaks debugging of a cell

+Fixed an interworking issue when running VSCode on Windows and connecting to a remote kernel that runs on some Unix distribution. Due to file path naming convention collisions, cell debugging failed.
