[pm-5287] fix account switch logout routing (#7231)

* Navigate to home from account switcher

Also updates the main background handling of logout to either finish switch or logout, depending on which occurred

* Prefer observable guards

we were racing the account switch process on `accountService` and this async guard. It only depended on account status, which is available from `accountService`, so the correct move was to observe that status.

The unauthGuardFn allows for updating homepage depending on window state because popout windows have different nav to other locations.
