Subject: [PATCH] Fix TypeError for views (#1045)

* Fix TypeError for views

quick and dirty fix, maybe this file needs some more cleanup

problem:
if you have `default_view` in groups.yaml and reload groups in `computeViewStates(currentView, hass, defaultView)`
`defaultView` is (still) defined but but `hass.states.group.default_view` doesn't exist

Fix: #893

* Update partial-cards.html

* Add ;

* Lint
