Title: Add custom Type, TypeExtension and TypeGessers in FormIntegrationTestCase

since 2.3 it's no longer possible to add Type to the Factory when using Symfony\Component\Form\Test\TypeTestCase as base class for tests. I porpose to add Types, TypeExtension and TypeGuessers during use of FormFactoryBuilder like it's already possible with Extensions.
I don't see another way to add custom Type (in my use case).
