Past Events are not shown after they have ended

Problem/Motivation

The following code does prevent to list the event in past events:

      case self::PAST_EVENTS:
        $this->query->addWhereExpression($this->options['group'], "
        (({$now} >= {$field_end}) AND ({$past_midnight} > {$field_end}))
        OR
        ({$field_end} IS NULL AND {$now} >= {$field})");
        break;

Proposed resolution

change the filter to:

      case self::PAST_EVENTS:
        $this->query->addWhereExpression($this->options['group'], "
        (({$now} >= {$field_end}))
        OR
        ({$field_end} IS NULL AND {$now} >= {$field})");
        break;
