Scheduled mail - Default value for number of days is wrong when having a positive number of days

#2 works but I would change the $days_options array to match the data that is stored for the handler. In #2 we add the + twice.

so do:

    foreach ($days as $day) {
      $days_options[$day] = $this->t('+ @day days', ['@day' => $day]);
    }

Or update the webform.handler.scheduled_email schema for the days key to store a string and not an integer (which is what is currently getting stored if you want to include the + in the value). But a schema change would break BC so we'd need an upgrade path for that, seems like a hassle.

Thanks for catching that.
