title: How to catch errors using Sequelize's findOrCreate()
body: <p>It seems I can only use the <code>.spread(user, created)</code> function and not the <code>.error()</code> function. I'm getting validation errors when trying to insert non-unique entries for testing and it's killing my node process.</p>
  
  <p>How can I catch errors from <code>findOrCreate</code>?</p>
