[console] Example by multiple InputOption triggers an Exception

[gcKevinAnneix]

Hi,

The following example in http://symfony.com/doc/current/components/console/introduction.html

->addOption(
    'iterations',
    null,
    InputOption::VALUE_REQUIRED | InputOption::VALUE_IS_ARRAY,
    'How many times should the message be printed?',
    1
);

triggers the following exceptions:

PHP Fatal error:  Uncaught exception 'LogicException' with message 'A default value for an array option must be an array.' in ..Console/vendor/symfony/console/Symfony/Component/Console/Input/InputOption.php:169

Stack trace:

Thank you for reporting this @kevinAnneix. This should be fixed with #4407.
