Copy and delete actions are proposed to the user even when she can't perform them

For instance, when listing the children of a page, if the current user does not have the view right on a child, the copy and delete action are displayed in the Actions column.

The links of the actions are http://localhost:8082/xwiki/bin/view/Sandbox/undefined and http://localhost:8082/xwiki/bin/view/Sandbox/undefined when listing the children of the Sandbox page.

Note: When migrated to Live Data, only the copy action is displayed unexpectingely.
