Fix breakdown of token.php after updateData

The content of the file (https://coderus.openrepos.net/whitesoft/whatsapp_classes) has a \n
after retrieving content and updating token.php, line 6 and 7 will be as follows:

```php
$classesMd5 = "Vu6nzOKzMttaMOYKo7YkEw==
"; // 2.11.419
```
After updating the file next time and replacing line 6 it will be just like so:

```php
$classesMd5 = "Vu6nzOKzMttaMOYKo7YkEw==
"; // 2.11.423
"; // 2.11.419
```
Therefore, the file is broken.
