Vim, Fuzzy: Update PHP private property completion.

Example:

    private array $list;

      |
      V

    /**
     * @var array
     */
    private $list;
Vim, Fuzzy: On completion, display a meaningful title.
Vim, Fuzzy: Require $this-> to be used in the PHP return completion.
Vim, Fuzzy: Whoops, debugging code left behind...
