MDL-20623 formslib: fixed multiple forms freezing

The singleton MoodleQuickForm_Renderer's property $this->_formTemplate
was set during the first frozen form display at a page and
such a frozen template remained for all other forms, too. This fix
returns the default form template for non-frozen forms.
