Make sure we don't go to the projects page when we just click open/close/delete

I had this error too a few days ago. It seems Firefox is reacting this way if you trigger two http requests very closely after each other. In this case you should add a _.delay(function () {$http.put( ... }, 200); to fix it for the firefox. I know it's an ugly solution, but it is way better than to ask for status code 0, since it does not have any statement. It can appear on success AND failure.
