NPE when defining a component using just t:id and no type or @Component 
annotation
----------------------------------------------------------------------------------

                 Key: TAP5-748
                 URL: https://issues.apache.org/jira/browse/TAP5-748
             Project: Tapestry 5
          Issue Type: Bug
          Components: tapestry-core
    Affects Versions: 5.1.0.5
            Reporter: Howard M. Lewis Ship
