Squiz.WhiteSpace.FunctionSpacing incorrect fix when spacing is 0

[JanGalek]

Fix this usecase:

Settings

spacing: 0
spacingBeforeFirst: 0
spacingAfterLast: 0

Code:

<?php
declare(strict_types = 1);

namespace Nette\CodingStandard\Examples;

interface OneBlankLineBeforeFirstFunctionClassInterface
{


    /** @return mixed */
    public function interfaceMethod();
}

it was returning this:

<?php
declare(strict_types = 1);

namespace Nette\CodingStandard\Examples;

interface OneBlankLineBeforeFirstFunctionClassInterface
{/** @return mixed */
    public function interfaceMethod();
}

it return now correct this:

<?php
declare(strict_types = 1);

namespace Nette\CodingStandard\Examples;

interface OneBlankLineBeforeFirstFunctionClassInterface
{
    /** @return mixed */
    public function interfaceMethod();
}

Thanks a lot for this report and PR. I ended up fixing this is a slightly different way so that it reflects how many of the other sniffs solve this problem, which is just to ignore any content of the same line as prevContent.
