Admin UI should stop polling event stats if the event tab isn't shown

Steps to reproduce

Steps to reproduce:
1. Open admin UI event view
2. change view to an other tab (like series)
3. show network log, you will see events.json stats requests are going on

Expected Results:
events.json requests should stop on an other view, as the data can not be rendered in the UI
