fix: choose() select path emits null label for emoji-only keys

add_option(label=label, ...) passed label=None straight through for an
emoji-only key (_split_key returns (None, emoji)), serializing
{"label": null, ...} which Discord's select-option schema rejects
(1-100 char label required). The <=5-option button path is unaffected
(a button may be emoji-only). Fall back to the key's own text form
(or a single space) as the label when _split_key yields none, so the
emoji is still shown via emoji= but the option always carries a
non-empty label.

Bump 0.1.1 -> 0.1.2.
