Fix clock preview when changin clock size

There are cases that when changing clock sizes, the clock preview
appears wrongly. This is due to that we resue the clock view and do
config changes to the view while they are in the clock carousel.

We need to always reset it to the original config when getting the
view again.

Test: See bug. Manually tested that the preview shows correctly
