Bugfix/status link update

REVIEW

The problem was, that the link in the status bubble was not updated without reloading the page. This happened, because in most cases the HTML division holding the link in the `.status` division was already present and therefore not updated with new information. The `.status` division is now cleared, so that a new and fresh url is inserted every time.
