LP1891355 Perm group refresh after changes

Fixes an issue where the permission group interface failed to refresh
the page after an edit and data refetch was performed.  At issue was a
progress component which was not rendered/active at the time of refresh,
leading to a JS error, causeing the refresh to stop.
