Digests recipient selection

[raboof]

lib/DigestSender.php is fetching users via $this->config->getUsersForUserValue('activity', 'notify_setting_activity_digest', '1');. This does not exclude disabled users on either side. Is this an oversight, or is the assumption that notify_setting_activity_digest should be disabled for disabled users?

(this is with Nextcloud 27.1.4, Activity 2.19.0)
