Yml serializer don't serialize empty arrays

[eduardosoliv]

    public function testEmptyArray()
    {
        $serializer = SerializerBuilder::create()->build();
        $ymlContent = $serializer->serialize(array('t' => array()), 'yml');
        echo $ymlContent; // prints t:

        // Symfony Yaml component
        print_r(Yaml::parse($ymlContent));
        print_r(Yaml::parse('t: []'));
    }

Running the test get:

t:
Array
(
    [t] => 
)
Array
(
    [t] => Array
        (
        )

)

Is this expected behavioral? Any way to configure it to serialize empty array as []?

Or is bug and should try to fix it in the code and open PR?

Looks like another inconsistency in serialization representation. In JSON empty arrays are serialized.

@entering @Tobion I wrote a PR to fix it. If you could please take a look. 👍
