Wiki SystemEvent

Hi Daniel,

I put send = false in the delete method but now I have another error in other test, 

 [junit] Testcase: testTrashAndDeleteApproved(com.liferay.portlet.wiki.trash.WikiPageTrashHandlerTest):	FAILED
    [junit] expected:<1> but was:<0>
    [junit] junit.framework.AssertionFailedError: expected:<1> but was:<0>
    [junit] 	at com.liferay.portlet.trash.BaseTrashHandlerTestCase.trashBaseModel(BaseTrashHandlerTestCase.java:656)

I'll try to add this code to the end of the delete method, like in journal, but I got another error.

```java

if (pageResource != null) {
			JSONObject extraDataJSONObject = JSONFactoryUtil.createJSONObject();

			extraDataJSONObject.put("version", page.getVersion());

			systemEventLocalService.addSystemEvent(
				0, page.getGroupId(), page.getModelClassName(),
				page.getPrimaryKey(), pageResource.getUuid(), null,
				SystemEventConstants.TYPE_DELETE,
				extraDataJSONObject.toString());
		}

```

Could you please help me with that? I think I'm missing something in WikiPageLocalServiceImpl.

Thanks very much!!!

Eudaldo.
