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.

scenario test for this example would be tricky, we need to teach
the runner how to inject mocks first.

the original test relied on incorrect assumptions about how jasmine async
tests work (when setTimeout is triggered) and how browser reloads a page
(the sequence of events) and thus the test passes even when the default
is not prevented.

this change fixes the test by registering an extra submit event handler
that checks if the default was prevented.

if the default was not prevented, the test will fail and the page will
be reloaded causing the test runner to panic.

this fix ensures that we prevent the default action on form submission
(full page reload) even in cases when the form is being destroyed as
a result of the submit event handler (e.g. when route change is
triggered).

The fix is more complicated than I'd like it to be mainly because
we need to ensure that we don't create circular references between
js closures and dom elements via DOM event handlers that would then
result in a memory leak.

Also the differences between IE8, IE9 and normal browsers make testing
this ugly.
