title: Sequelize not updating Meta table after applying migration
body: <p>I don't know if I'm missing a step here or something, but <code>sequelize</code> is not updating the <code>SequelizeMeta</code> table after I run a migration.</p>
  
  <p>If I run <code>db:migrate:status</code> I get that all my migrations are "up" but the last one, which doesn't even appears in the output.</p>
  
  <p>Do I have to update this table manually?</p>
  
  <p>[<strong>EDIT</strong>]</p>
  
  <p>I've been looking more closely at the <code>sequelize db:migrate</code> command's output:</p>
  
  <pre><code>Executing (default): INSERT INTO "SequelizeMeta" ("name") VALUES ('20180827001615-updatePersonIdColumn.js') RETURNING *;
  
  ERROR: null value in column "createdAt" violates not-null constraint
  </code></pre>
  
  <p>Looks like there is no default for the "createAt" column. Is this normal?</p>
