stream_edit: Fix bug of disabling of "Add" button on subscribing. 

We live update the "Add subscribers" UI on subscribing/unsubscribing
the stream and the field sub.can_add_subscribers is used to check
whether user is allowed to add subscribers or not.

The sub object used here is not the complete sub object and thus
sub.can_add_subscribers is undefined. We need to use the updated
sub obejcts with all the setting fields that we can get from
'stream_settings_data.get_sub_for_settings' before rendering UI.

This calculation of additional fields was done previously by
'stream_data.update_calculated_fields', but in d50462568b
call to 'updated_calculated_fields' was removed with the aim to
call 'get_sub_for_settings' before updating UI which was missed
in this part of UI update.

Fixes #18616.
