test: don't sort expected completion lists under the hood

We need to match the order in which bash lists completions, which may
not be a straightforward one. For example, it seems to add slashes after
sorting dir completions without changing the sort order. For example
"foo" sorts before "foo-bar", but "foo/" after "foo-bar/", but the order
of completion output is "foo/" followed by "foo-bar/". Test cases should
sort their lists explicitly where appropriate.
