[PATCH 3/4] fix output for deleted submodules in git diff --submodule-summary

[Jens Lehmann <Jens.Lehmann@web.de>]

When a submodule has been deleted, add_submodule_odb() returns false
because the directory of the submodule is gone. So we have to test the
second sha for null before we call add_submodule_odb() to get the correct
output.
