title: Extjs6 Dependency Issues with workspace packages
body: <p>I have created a sencha package "common" using the sencha command:</p>
  
  <pre><code>sencha generate package common
  </code></pre>
  
  <p>and placed a file in the workspace/packages/local/src called "mytext.js":</p>
  
  <pre><code>Ext.define('Common.mytext',{
      extend: 'Ext.form.field.Text',
      xtype: 'mytext',    
      initComponent: function(){
          Ext.apply(this,{
              onBlur: function(){     
                //Set The corrected value for the field       
              }
          });
          this.callParent(arguments);     
      }
  });
  </code></pre>
  
  <p>In my main application, I include the requirement "common" in my app.json file.</p>
  
  <p>When I do a<code>sencha app refresh</code> I get the following dependency errors:</p>
  
  <pre><code>[ERR] Failed to resolve dependency Ext.form.field.Text for file Common.mytext
  [ERR] 
  [ERR] BUILD FAILED
  [ERR] com.sencha.exceptions.ExNotFound: Unknown definition for dependency : Ext.form.field.Text

  <p>Am I missing some configuration?  Thanks.</p>
