reproducer bug 3634

repro for phpstan/phpstan#3634

how to reproduce

• clone the repo
• run composer install
• run vendor/bin/phpstan analyze -c app/phpstan.neon --debug -> 'Call to an undefined method HttpResponse::deleteCookie()' error

expected result: no error, since the composer loadable HttpResponse should be preferred over the HttpResponse class from PHPStorm stubs.
