Validating arrays with distinct rule involves attributes in nested arrays

[denho]

• Laravel Version: 5.3.22
• PHP Version: 7.0.10

Description:

In docs for distinct validation rule it is written: "When working with arrays, the field under validation must not have any duplicate values.". But it checks not only the exactly the matching field, but all nested fields with the same attribute name. E.g. 'foo.*.id' => 'distinct' will check not only foo.0.id, foo.1.id,.. but also foo.0.nested.id.
The reason is that Str::is($attributeName, $key) matches not only foo.0.id or foo.1.id, but also foo.0.whatever.id

Steps To Reproduce:

$array = [
 'foo' => [
    ['id' => 1, 'nested' => ['id' => 2]],
    ['id' => 2],
  ]
];

$validator = Validator::make($array, [
  'foo.*.id' => 'distinct'
]);

if($validator->fails())
 dd($validator->errors());

will fail and return "The foo.1.id field has a duplicate value."
