title: Sequelize-cli doesn't do anything
body: <p>I am trying to use sequelize and sequelize-cli to create database schema changes (MSSQL) by using the migration mechanism. But nothing is happening - it looks like it does not find any migration files in the migration folder.</p>
  
  <p>I did the following in a new folder to create a test project:</p>
  
  <pre><code>npm init
  [ added relevant packages: sequelize, sequelize-cli, tedious ]
  sequelize init
  [ here I added the connection information, all to a blank database on Azure SQL ]
  sequelize init:models
  sequelize init:migrations
  sequelize migration:create
  </code></pre>
  
  <p>I added the following to the created migration file:</p>
  
  <pre><code>'use strict';
  module.exports = {
  up: function (queryInterface, Sequelize) {
  return queryInterface.createTable('users', { id: Sequelize.INTEGER });
  },
  down: function (queryInterface, Sequelize) {
  return queryInterface.dropTable('users');
  }
  };
  </code></pre>
  
  <p>which is basically just according to the template created by the last sequelize command.</p>
  
  <p>Now I would expect a new table to be created when I run the migrate command:</p>
  
  <pre><code>sequelize db:migrate
  </code></pre>
  
  <p>But all I get is this:</p>
  
  <pre><code>Sequelize [Node: 0.12.2, CLI: 1.7.4, ORM: 3.5.1]
  Loaded configuration file "config/config.json".
  Using environment "development".
  Using gulpfile /usr/local/lib/node_modules/sequelize-cli/lib/gulpfile.js
  Finished 'db:migrate' after 161 ms
  </code></pre>
  
  <p>which means it did not find any migration files. No table has appeared in the database and no sequelizeMeta table was created.</p>
  
  <p>What's wrong?</p>
