This PR simply adds a dependency on php7-xmlwriter to the php-fpm Dockerfile.
The reasoning behind this, is that when using Symfony 4, after installing symfony/test-pack, running phpunit, will cause PHPUnit 6.5 to be installed, but the dependency cannot be installed, as the docker container's php does not have access to ext-xmlwriter and phpunit's code coverage library relies on it.
