Having trouble closing db connection

[StefanoDeVuono]

When I run my test, the database connection stays open at the end, even if I ask to close it:

const wtf = require('wtfnode');

const test = require('tape'),
      db = require('seraph')({
        bolt: true,
        nodeify: true,
        pass: process.env.NEO4JPASSWORD
      });

test('nothing', t => {
  const person = { name: 'Jon', age: 22, likes: 'Beer', test: true };
  db.save(person, function(err, node) {
    let testNode = Object.assign({}, node);
    delete testNode.id;
    t.deepEqual(testNode, person);
    t.end();
  })
})

test.onFinish( () => {
  db.close();
  wtf.dump();
});

wtf shows an open socket, even though I've asked to close my db connection:
127.0.0.1:51255 -> 127.0.0.1:7687

I think this is due to the close method in seraph/bolt calling this.options.session && this.options.session.close();. Since there is no session object on the options key, the close method just returns undefined.

I've did the same test with the official neo4j driver which leaves an open db connection, too.

const wtf = require('wtfnode');
const neo4j = require('neo4j-driver').v1;

// Config
const { NEO_URI, NEO_USER, NEO_PASS } = require('../config/keys');

// Neo4j
const driver = neo4j.driver(NEO_URI, neo4j.auth.basic(NEO_USER, NEO_PASS));
const session = driver.session();

const personName = 'Alice';
const resultPromise = session.run('CREATE (a:Person {name: $name}) RETURN a', {
  name: personName
});

resultPromise
  .then(result => {
    session.close();

    const singleRecord = result.records[0];
    const node = singleRecord.get(0);

    console.log(node.properties.name);

    // on application exit:
    driver.close();
  })
  .then(res => wtf.dump());
