Fix order of cleaning up constants docs

[krzysztofrewak]

Right now this:

    /** @var string */
    public const DEBUG = "debug";
    /** @var string */
    public const INFO = "info";
    /** @var string */
    public const NOTICE = "notice";
    /** @var string */
    public const WARNING = "warning";
    /** @var string */
    public const ERROR = "error";
    /** @var string */
    public const CRITICAL = "critical";
    /** @var string */
    public const ALERT = "alert";
    /** @var string */
    public const EMERGENCY = "emergency";

is reformatted into this:

    public const DEBUG = "debug";

    public const INFO = "info";

    public const NOTICE = "notice";

    public const WARNING = "warning";

    public const ERROR = "error";

    public const CRITICAL = "critical";

    public const ALERT = "alert";

    public const EMERGENCY = "emergency";

... and after secound run, into this:

    public const DEBUG = "debug";
    public const INFO = "info";
    public const NOTICE = "notice";
    public const WARNING = "warning";
    public const ERROR = "error";
    public const CRITICAL = "critical";
    public const ALERT = "alert";
    public const EMERGENCY = "emergency";

Probably we should change order of some fixers to receive a proper result after first run. It should be added to tests too.
