[Php71] Skip already array destruct on ListToArrayDestructRector

[samsonasik]

Given the following code:

<?php

namespace Rector\Tests\Php71\Rector\List_\ListToArrayDestructRector\Fixture;

final class SkipAlreadyArrayDestruct
{
    public function run($line, $file, $trace)
    {
        [
            'line' => $line,
            'file' => $file,
        ] = $trace;
    }
}

It somehow reprinted:

There was 1 failure:

1) Rector\Tests\Php71\Rector\List_\ListToArrayDestructRector\ListToArrayDestructRectorTest::test with data set #2 ('/Users/samsonasik/www/rector-...hp.inc')

+        ['line' => $line, 'file' => $file] = $trace;

which should be skipped. This PR try to fix it.
