stash show: fix segfault with --{include,only}-untracked
When `git stash show --include-untracked` or
`git stash show --only-untracked` is run on a stash that doesn't include
an untracked entry, a segfault occurs. This happens because we do not
check whether the untracked entry is actually present and just attempt
to blindly dereference it.
Ensure that the untracked entry is present before actually attempting to
dereference it.
