completions/set: strip cursed descriptions from history/fish_killring

Browse Source 
If I type

    $ echo $SOME_VARIABLE_WIHT_A_TYPO
    $ set -S SOME_VARIABLE_WIHT

and press tab, I'm always extremely surprised that this completes to

    $ set -S fish_history

which is because $history[1] contains the typo'd variable name.  I don't
think anyone intends to filter by that last 3-4 history items, so let's
remove this pitfall.

Note that I usually hit this scenario with undefined variables, not necessarily
typos.. "set -S" is usually redundant but it's still quite nice in this case,
to rule out any weird empty strings/empty lists.
