[Fast Refresh] Reorder Loaders

[Timer]

This reorders the fast refresh loader so that it does not influence Babel syntax errors, obscuring the real problem.

Without this, the user sees something like:

    SyntaxError: /Users/joe/Documents/Development/Work/zeit/next.js-extra/test/acceptance/__tmp__/fiuG3UK5eJ3kqLTI4GNv5/index.js: Unexpected token (17:8)

      15 |     // browser context before continuing.
      16 |     if (typeof self !== 'undefined') {
    > 17 |         var currentExports_1 = module.__proto__.exports;
         |         ^
      18 |         var prevExports = (_b = (_a = module.hot.data) === null || _a === void 0 ? void 0 : _a.prevExports) !== null && _b !== void 0 ? _b : null;
      19 |         // This cannot happen in MainTemplate because the exports mismatch between
      20 |         // templating and execution.
