Use generateBundle instead of onwrite

Fixes #147

The onwrite rollup hook has been deprecated in favor of generateBundle in rollup@1.x.x. rollup/rollup#2409

Can you update the snapshots in the tests?

[sampi]

@nathancahill hey, I did but something doesn't look ok, and the order of the css rules aren't deterministic. (no matter if I update the snapshots or not, it fails)

I'll have to investigate a bit more.

PR #143 should fix the order of css rules, and make the order deterministics.

However, with the new generateBundle, the code:

        const entries = Array.from(extracted.values())
        if (bundle.modules) {
          const fileList = Object.keys(bundle.modules)
          entries.sort((a, b) => (
            fileList.indexOf(a.id) - fileList.indexOf(b.id)
          ))
        }

should become:

        const entries = Array.from(extracted.values())
        const { modules } = bundle[path.basename(opts.file)]
        if (modules) {
          const fileList = Object.keys(modules)
          entries.sort((a, b) => (
            fileList.indexOf(a.id) - fileList.indexOf(b.id)
          ))
        }
