Prettify the output of Zend\Code\Generator\ValueGenerator for multi line arrays

[RalfEggert]

This fix prettifies the output for multi line arrays generated with Zend\Code\Generator\ValueGenerator

Without this fix, an array looks like this.

array(
    'controllers' => array('invokables' => array(
            'Event\Controller\IndexController' => 'Event\Controller\IndexController',
            'Event\Controller\ShopController' => 'Event\Controller\ShopController',
            )),
    'view_manager' => array('template_path_stack' => array(__DIR__ . '/../view'))
    )

With the fix, the same array will look like this:

array(
    'controllers' => array(
        'invokables' => array(
            'Event\Controller\IndexController' => 'Event\Controller\IndexController',
            'Event\Controller\ShopController' => 'Event\Controller\ShopController',
        )
    ),
    'view_manager' => array(
        'template_path_stack' => array(
            __DIR__ . '/../view'
        )
    )
)

Please note the changes for the entry for 'view_manager' and the positions of the braces.

@RalfEggert Update the unit tests please, there are some fails https://travis-ci.org/zendframework/zf2/jobs/15495156#L281

[RalfEggert]

Sorry, forgot about that. The unit tests are fixed now...

[blanchonvincent]

@RalfEggert https://travis-ci.org/zendframework/zf2/jobs/15509026#L269 :)

[RalfEggert]

To be honest, I don't really understand what failed there... :-(

@RalfEggert the closing parenthesis of the expected value is indended 4 spaces to much. https://github.com/RalfEggert/zf2/blob/0413da7532bc8e28e18527af18ac1ad9875cfb90/tests/ZendTest/Code/Generator/PropertyGeneratorTest.php#L108

@Netiul Thanks, I just checked the ValueGeneratorTest and missed that one. Now it should work...

[blanchonvincent]

@RalfEggert 👍

In this case the close parenthesis should not be indented
