Searching with dates throw error after #1783746

After upgrading to 7.x.1.25 the bellow error begun:
Warning: Illegal string offset 'value' in SearchApiViewsHandlerFilterDate->query() (line 154 of ***/www/html/sites/all/modules/search_api/contrib/search_api_views/includes/handler_filter_date.inc).

Tracked this issue to
https://www.drupal.org/node/1783746
https://www.drupal.org/files/issues/2018-05-15/1783746-92--between_opera...

Outlining the issue from the change:

    else {
      while (is_array($this->value)) {
        $this->value = $this->value ? reset($this->value) : NULL;
      }
      $v = is_numeric($this->value) ? $this->value : strtotime($this->value, REQUEST_TIME);
      if ($v !== FALSE) {
        $this->query->condition($this->real_field, $v, $this->operator, $this->options['group']);
      }
    }

      $value = isset($this->value[0]) ? $this->value[0]['value'] : $this->value['value'];
      $v = is_numeric($value) ? $value : strtotime($value, REQUEST_TIME);
      if ($v !== FALSE) {
        $this->query->condition($this->real_field, $v, $this->operator, $this->options['group']);
      }

Output from this variable just before the error:

SearchApiViewsHandlerFilterDate Object
(
    [value] => Array
        (
            [0] => 2018-10-01
        )

It seems that the structure of the object is different than anticipated in the change done.

The fix I used and works for me, but not sure if it should be rolled back to the way it was.

--      $value = isset($this->value[0]) ? $this->value[0]['value'] : $this->value['value'];
++      $value = isset($this->value[0]) ? $this->value[0] : $this->value;

Also there is an empty line to be removed on line 160.

Using datepicker for the date selection.
