Bug report

Describe the bug

My app of next@9.0.4-canary.3 raise error in safari.

main.js

function markHydrateComplete() {
  if (!_utils.SUPPORTS_PERFORMANCE_USER_TIMING) return;
  performance.mark('afterHydrate'); // mark end of hydration

  performance.measure('Next.js-before-hydration', null, 'beforeRender');
  // => SyntaxError: The string did not match the expected pattern.
  performance.measure('Next.js-hydration', 'beforeRender', 'afterHydrate');
  clearMarks();
}

it seems that safari doesn't exec with second args.

To Reproduce

1. Create next app
2. Upgrade next to 9.0.4-canary.3
3. Start dev server
4. Open broswer

Expected behavior

Safari does not raise a error.

Screenshots

System information

• OS: macOS 10.14.4
• Browser (if applies): Safari 12.1
• Version of Next.js: 9.0.4-canary.3

Safari doesn't seem to allow null, so we should explicitly pass navigationStart:

performance.measure('Next.js-before-hydration', 'navigationStart', 'beforeRender');
