Suggestion; Add `onFinish` prop.

[NishidaRyu416]

When finishing adding tags, if the last one is not made a tag by a comma, space or something preferred, the one ends up not being a tag successfully.
So I suggest that you should add a prop called onFinish with a boolean argument to make the very last one a tag automatically.

I love that, thanks for the suggestion.
