* REPO-2819 : DELETE /shared-links/{id} with admin returns 403
Add an extra check to QuickShareServiceImpl.canDeleteSharedLink, because the admin user can return the SiteName of a nodeRef (even if it's private).
Add a JUnit test into QuickShareServiceIntegrationTest
Add a comment to the test - no actual shared Link is needed for this test.
* REPO-2520 : SiteMembership Java API calls should tell which site resulted in errors
Add the test class into the test suite (was not previously added).
