URLPattern: Fix matched values for ':name*' patterns.

This fixes the problem where:

  const p = new URLPattern({ pathname: ':name*' });
  const r = p.exec('foobar');
  console.log(r.pathname.groups.name);

Would log 'r' instead of 'foobar'.

This is an upstream bug in path-to-regexp as well:

pillarjs/path-to-regexp#260
