Include segments broken - Send custom notification

[Sml995]

In the last release an additional check is performed before setting $parameters['included_segments'] = ['All'] by default in sendNotificationCustom()

However the check is on the string instead of the array index:

empty('include_external_user_ids')

Should be:

empty($parameters['include_external_user_ids'])
