Serialization error when using a cache

[mnapoli]

When defining a ValueDefinition with

$container->set('foo', $var);

ValueDefinition::isCacheable() will return false if $var is an object.

However, if $var is an array containing unserializable objects, PHP-DI will try to serialize it (and thus an exception will be thrown).

On a more general note, I think it's absurd to cache a ValueDefinition, their nature is dynamic (they can be depending on something, the user, the session, …).

So ValueDefinition shouldn't be cached anymore.

Fixed in 3.1.1
