stash: handle staged changes in skip-worktree files correctly
When calling `git stash` while changes were staged for files that are marked with the `skip-worktree` bit (e.g. files that are excluded in a sparse checkout), the files are recorded as _deleted_ instead. The reason is that `git stash` tries to construct the tree reflecting the worktree essentially by copying the index to a temporary one and then updating the files from the worktree. Crucially, it calls `git diff-index` to update also those files that are in the HEAD but have been unstaged in the index. However, when the temporary index is updated via `git update-index --add --remove`, skip-worktree entries mark the files as deleted by mistake. Let's use the newly-introduced `--ignore-skip-worktree-entries` option of `git update-index` to prevent exactly this from happening. Note that the regression test case deliberately avoids replicating the scenario described above and instead tries to recreate just the symptom. Reported by Dan Thompson.
