Cannot install statistics UI through EM

Tested on a clean instance of XE 8.2

1. Go to xwiki.cfg and set:

• xwiki.stats =1
• xwiki.stats.default=1

2. Start the instance and open it in browser.
3. Login with Admin and search for Statistics app in EM.

Actual result:

• You don`t find the statistics app in EM search results.
• In the documentation pages related to the extension or into Admin`s guide, there is no id which you can use to perform an advanced search.
• You must go to github to find this id : org.xwiki.platform:xwiki-platform-statistics-ui (8.2)

Expected Result:

• Even if the app is not installed by default any more, you should be able to access it through EM and install it.
