Subject: fix($location): url rewriting if element was removed

When user clicks a link, $location needs to intercept this event.  The <a> doesn't have to be target element of the DOM event, so it needs to traverse the DOM, to find first <a> parent.

If the target element was removed from DOM, during the same event, it would throw an exception. This fixes the issue.
