Fixed coding standard violations in the Framework\Stdlib namespace, so that it will be checked bij PHP CS and no longer be ignored while doing CI checks. Made the following changes:

- Removed @codingStandardsIgnoreFile at the head of the files
- Fixed indentation
- Fixed class property which type was not defined.
- Wrapped header of PhpCookieManagerTest with a codingstandardignorestart and end, because another namespace is given in the same class file, which is not allowed by PSR-2
