Improve pdo_sqlite using info

1. Line with `path` declaration should be uncommented in config.yml for use `database_path`
2. Line with `database_path` declaration should be uncommented in parameters.yml.dist, because any composer commands (which call `post-install-cmd` or `post-update-cmd`) remove `database_path` from parameters.yml
