fakeHttp() should call FinalizerInterface after each request

[chiost]

Problem

fakeHttp() does not call FinalizerInterface::finalize() after handling
requests.

In production with RoadRunner, Http\Dispatcher calls
$this->finalizer->finalize(false) after each request. This triggers
cleanup registered by bootloaders (e.g., Cycle ORM heap cleanup in
CycleOrmBootloader).

Since fakeHttp() bypasses the dispatcher, finalizers are never called,
causing state to leak between sequential requests in the same test.

Suggestion

Call FinalizerInterface::finalize(false) in FakeHttp::handleRequest()
after processing the request, matching the RoadRunner dispatcher behavior.

Sounds logical. Would you like to create a PR?
