title: sequelize.js how can I reconnect after close
body: <p>I use the sequelize.js to connect sqlite, but I must to close the connect because I want to modify the sqlite's file. Windows cannot modify the file when it's opening.</p>
  <p>I create the object like this:</p>
  <pre class="lang-js prettyprint-override"><code>const sequelize = new Sequelize('database', null, null, {
      dialect: 'sqlite',
      storage: 'db.sql',
      define: {
        timestamps: false,
        freezeTableName: true
      },
      dialectModule: sqlite3
    })
  </code></pre>
  <p>And when I close the connect, I cannot reconnect sqlite by the original object.
  I try to use the ConnectionManager initPools, but it does not work.</p>
  <pre class="lang-js prettyprint-override"><code>sequelize.close()
  // do something ...
  sequelize.connectionManager.initPools()
  sequelize.authenticate() // raise the error by disconnect
  </code></pre>
