FIX: CurrentUser now must be passed to resolveTimezone and user card local time issues (#9734)

* This is to prevent user's timezones being changed accidentally
e.g. by admin looking at a user
* This problem only occurred via the user card, however the user card
was still calling userTimezone even if the setting to display user
time in card was disabled
