inline reply js errors if wpadminbar is not present

[rmessick]

Users that do not have the wpadminbar turned off when replying inline there is js error in reply.js that causes the page to refresh which in turn moves the reply form to the bottom of page.

          , d = e.getElement("wpadminbar")
          , l = 0;
        void 0 !== d && (l = d.scrollHeight),

When adding the wpadminbar it works as intended.
