Subject: Use window.hasOwnProperty for window._qutebrowser

With an element like this in the page:

    <h2 id="_qutebrowser">qutebrowser</h2>

accessing window._qutebrowser will return the HTMLElement (thanks, JS...),
making qutebrowser's JS think it's already initialized when it actually isn't.

Fixes #4633
