v3.12.1

This version fixes a bug where the following happo example file would silently fail (render no examples at all or only some). The problem was most apparent when the happo-plugin-puppeteer plugin was used.

export foo = () => <i>Hello world</i>;
export bar = <i>Hello world</i>;

(notice the missing function wrapper for bar).

The fix involved adding validation early in the process and throwing an error when a render-less example was found.
