Integration test ITD not updated when entity's plural changes

To replicate:

1. Run the vote.roo script
2. Using a text editor or IDE, add the class-level annotation @RooPlural("Things") to Vote.java; Roo correctly updates these files:

   Updated SRC_MAIN_JAVA/com/springsource/vote/web/VoteController_Roo_Controller.aj
   Updated SRC_MAIN_JAVA/com/springsource/vote/domain/Vote_Roo_Entity.aj
   Updated SRC_MAIN_WEBAPP/WEB-INF/views/votes/list.jspx

3. Restart the Roo shell; only now does Roo update the integration test ITD:

   Updated SRC_TEST_JAVA/com/springsource/vote/domain/VoteIntegrationTest_Roo_IntegrationTest.aj

Likewise, if you delete that annotation to restore the default pluralisation, the same ITD is not updated until you restart the Roo shell.
