Method signature inheritance issue

[szepeviktor]

AbstractSniffAnalyser::beforeTraverse has {@inheritDoc} and ❗ it works 😃

PhpParser\NodeVisitor::beforeTraverse looks like

https://github.com/nikic/PHP-Parser/blob/master/lib/PhpParser/NodeVisitor.php#L7-L18

so we should return null|Node[] and phpstan tells us exactly that.

  62     Method Bartlett\CompatInfo\Application\Analyser\AbstractSniffAnalyser::beforeTraverse() should return
         array<PhpParser\Node>|null but return statement is missing.

Adding a return statement will resolve this and all other problems of this kind.
