RecursiveDirectoryIterator due to symbolic links in main folders

[dunebaud]

How is drupal-check installed?

• drupal-check is installed globally via Composer

Environment:

• OS: Linux
• PHP Version: 7.2
• Drupal core: 8.x.x

Describe the bug
I ran drupal-check -d . from within my drupal directory and I got failed to open dir: Too many levels of symbolic links

Console output
`In RecursiveDirectoryIterator.php line 91:
RecursiveDirectoryIterator::__construct(/var/www/html/d8mbs4/my_site/my_site/my_site/my_site/my_site/my_site/my_site/my_site/my_site/my_site/my_site/my_site/my_site/my_site/my_site/my_site/my_site/my_site/my_site/my_site/my_site/my_site/my_site/my_site

This is due to the fact that I have symbolic links in the drupal root (this is required in multi site environment)...
I have also other symlinks pointing to custom modules to ease my dev (not required by Drupal installation)

Removing all those symlinks remove my problem

I have a similar issue on any of my projects that use the kporras07/composer-symlinks composer package to link custom modules/themes.

Parser.php returns an error for Duplicate key "services" detected at line 6.

So this is either a problem with PHPStan or the webflo/drupal-finder package.

I don't plan on chasing these bugs. It's a problem in phpstan-drupal or PHPStan. Not something to be fixed here though.
