Custom templates bug

There's a small bug, which makes using custom templates impossible. In com_communitypolls/controllers/polls.pp, line 412:

$tpl = !empty($poll->params) ? JFile::makeSafe($params) : 'default';

Should be this instead:

$tpl = !empty($params) ? JFile::makeSafe($params) : 'default';

Please, fix this.
