Fix: remove comma in Caddy and EVCC widgets

[grimsi]

Proposed change

Commit 19c25713c42c25795e117d2f75d92f69c4211f38 introduced a very minor layout bug to my Caddy and the EVCC widget (a comma character in the layout block of the widget). It just shows up when the API call for the widget is still loading so it's very hard to notice, but once you do notice it the first time, you will notice it every time 😉

I did not create a bug report since the issue is very minor. If necessary I can create one however.
