title: Don't know how to build task 'db:create'
body: <p>I'm migrating from a sqllite db to mysql2.  I have mysql running (and changed database.yml) but for some reason my rake db:create comes back with:</p>
  
  <pre><code>rake aborted!
  Don't know how to build task 'db:create'
  </code></pre>
  
  <p>When I do a:  rake -T, no db tasks appear in the list.</p>
  
  <p>I'm on Rails 3.2.9</p>
  
  <p>What obvious thing am I missing here?</p>
