title: CConsoleApplication.defaultController not defined when creating new migration
body: <p>I'm trying to use the yii migration system but I'm stuck on this error when I execute this commande:</p>
  
  <pre><code>yiic migrate create add_table_test
  </code></pre>
  
  <p>I get this error:</p>
  
  <pre><code>exception 'CException' with message 'Property   CConsoleApplication.defaultController" is not defined'
  </code></pre>
  
  <p>(CCompenent.php:173)</p>
  
  <p>But I've defined a defaultController in my config file:</p>
  
  <pre><code>'basePath'=&gt;$rootPath,
  'defaultController' =&gt; 'person/index',
  'homeUrl'=&gt;array('/me'),
  </code></pre>
  
  <p>I spent hours looking on Google, but I can't find a solution.</p>
  
  <p>Does anyone have an idea about this problem?</p>
