Hidden files ignored even if explicitly defined

[Rasmus-Bertell]

Describe the bug

I have two identical files app/Models/Locale.php and app/Models/.Locale.php phpcs only reports the errors on the first one and phpcbf only fixes the first one.

Code sample

<?php return FALSE;

To reproduce

Steps to reproduce the behavior:

1. Create a file called test.php with the code sample above
2. Copy the file cp test.php .test.php
3. Run phpcs test.php
4. Run phpcs .test.php
5. Run phpcbf test.php
6. Run phpcbf .test.php

$ phpcs test.php
