Decode HTML entities by default on node/server

Set parser options `decodeEntities` to true for `html-dom-parser`,
which gets passed to `htmlparser2`.

Write test to confirm that entities passed to React element's
children are decoded (but they will still be encoded when rendered
by ReactDOMServer).
