Node::isEqual not properly comparing nodes with array properties #88
Description
A signature such as public function find($id, $columns = ['*']) contains an Array_ expression, which itself contains $items = []. When we iterate over the properties of a node, we should check if it is an array and if so, test if each corresponding elements is a \PhpParser\Node (and recursively call Node::isEqual) or directly compare the two.
Another simple and dirty solution would be to reuse the code in \PHPSemVerChecker\Comparator\Implementation (using the \PhpParser\NodeDumper and check for dump identicality).
