Laravel, Collision & PHPUnit: Terminal shows warning "Option --configuration cannot be used more than once"

[Tjaitil]

Hello,

When running PHPUnit tests in a Laravel project with a different PHPUnit configuration,
e.g php artisan test --configuration phpunit.foo.xml the terminal produces a warning.

"WARN  Option --configuration cannot be used more than once".

Was mentioned as a collision issue and fixed via a PR in this repo. The original fix has since been removed in commit. So the --configuration flag is passed by default, see TestCommand.

Interestingly enough the warning doesn't appear when using php artisan test -c phpunit.foo.xml. Even though -c and the --configuration is the same according to phpunit.

Reproducable steps in a new laravel project

1. Create a new laravel project with phpunit
2. Copy phpunit.xml to phpunit.foo.xml or whatever *.xml
3. Run php artisan test --configuration phpunit.foo.xml

I would happy to provide a repoducable repo. Thanks in advance.
