cherry-pick will segfault when transplanting a root commit if the --ff option is used. This happens because the "parent" pointer is set to NULL when the commit being cherry-picked has no parents. Later, when "parent" is dereferenced, the cherry-pick segfaults. Fix this by checking whether "parent" is NULL before dereferencing it and add a test for this case of cherry-picking a root commit with --ff.
