Subject: [PATCH] Fixed TreeBuilder::root() symfony 4.3 deprecation (#21)

* Fixed symfony 4.2 deprecation

The "Symfony\Component\Config\Definition\Builder\TreeBuilder::root()" method called for the "qp_woohoolabs_yin" configuration is deprecated since Symfony 4.3, pass the root name to the constructor instead

* [patch-1] Use BC layer for deprecation in symfony/config

see https://github.com/symfony/maker-bundle/pull/324 and https://github.com/doctrine/DoctrineBundle/pull/853

Remove the BC layer when bump to next major version.
