Rename template depends on a XAR extension

Steps to reproduce:

1. Clone https://github.com/xwiki/xwiki-platform
2. Open a console
3. Navigate to "xwiki-platform\xwiki-platform-core\xwiki-platform-flamingo\xwiki-platform-flamingo-skin\xwiki-platform-flamingo-skin-test\xwiki-platform-flamingo-skin-test-tests"
4. Run "mvn clean install"
5. Inside the target folder you have a xwiki folder -> open XWiki from there
6. Go to http://localhost:8080/xwiki/bin/view/Main/
7. Pick Rename from the options
8. Choose a new location
9. Check the "AUTOMATIC REDIRECT" checkbox
10. Click Rename
11. Open the "Rename Log"

You will see 2 warning lines similar to this one:

We can't create an automatic redirect from [Home » Main » WebHome] to [Home » goa » yolo » WebHome] because [Home » XWiki » RedirectClass] is missing.

The Rename operation succeeds, but the "AUTOMATIC REDIRECT" feature is not working.
