replace isset to empty

IF statement ! isset($this->uiprefs) was causing issue.

Private property 'uiprefs' is initialized to empty array, so ! isset($this->uiprefs) is always FALSE;
It's not hopefull, so I replace ! isset($this->uiprefs) to empty($this->uiprefs) to fix #17617 bug;

Fixes #17617
Closes #17644
