Fix integration tests by fixing a PHP 8.1+ deprecation warnings in ReflectionClass (#1351)

* gha: get more insights when/if logs exist

* Better handle cases when we can receive a concrete instance

The problem with `null` being passed to `ReflectionClass` was always
there but in PHP 8.1+ it triggers a deprecation warnings.

Since having `null` in `$concrete` doesn't make sense to reflect
anything anyway, we just throw a custom exception (which gets caught a
couple lines below) and just carry on.

When using `-v` this can be seen, example:
```
$ ./artisan ide-helper:meta -v
Cannot make 'Faker\Generator': Class 'Faker\Provider\en_US\Barcode' not found.
Cannot make 'Illuminate\Contracts\Auth\Authenticatable': Class  does not exist
Cannot make 'cache.psr6': Class 'Symfony\Component\Cache\Adapter\Psr16Adapter' not found.
Cannot make 'csp-nonce': Class 'Wza3Mf4CXIvCkcp9K3boMUGJoK6S9maO' not found.
Cannot make 'env': Class 'local' not found.
Cannot make 'filesystem.cloud': Disk [s3] does not have a configured driver.
Cannot make 'redis.connection': Redis connection [default] not configured.
A new meta file was written to .phpstorm.meta.php
```

* gha: make sure to run meta with -v to see all output

Helps when debugging things

* Add CHANGELOG.md entry
