Add line break between opening tag and namespace in generated files

[Naktibalda]

Test and Cest generators generate namespace on the same line as opening tag.
e.g.

<?php namespace foo;

This change changes it to

<?php
namespace foo;

[TavoNiievez]

after I generate a Test, I always change:

<?php namespace App\Tests;

class MyTest extends \Codeception\Test\Unit

by:

<?php

namespace App\Tests;

use Codeception\Test\Unit;

final class MyTest extends Unit

could this be the default behavior?

I think that will be a part of #6071.

[Naktibalda]

I misread the question last night, so it probably won't be a part of that pull request.

[DavertMik]

@Naktibalda yes, let's make it part of #6071

[DavertMik]

The original idea of this was to not introduce empty line if no namespace is used

[Naktibalda]

@DavertMik this is a non-breaking change, so it can be merged to 4.1.
4.1 isn't dead yet.
