Dashboard bug

[Corginyan]

I noticed a bug when switching dashboards. Sometimes the dashboard is displayed empty. I investigated the source code a bit and found an interesting place in the Dashboard component. Most likely, a race starts here and sometimes the response from the api with empty data comes later than the data of the selected dashboard. If you do

setElements({});
setElements2([]);
setPathes([]);

instead of requesting the api for an empty dashboard, it seems to solve the problem.
