A tag on the Home page shows that the tag is used on 4 pages in the list of tags

Steps to reproduce:

1. Log in as a simple user or Admin
2. Click on Home page
3. Add a tag
4. Go to the Tag list (http://localhost:8080/xwiki/bin/view/Main/Tags)
5. Hover over the tag to see in how many pages this is used
6. Click on the tag

Expected results: Hovering over the tag shows the exact number of pages it is used in. When clicked the list of pages is shown.

Actual results: Tags used in Home page show as being used in 4 pages in the tag list. When tag is clicked only the Home page appears - tag used in only 1 page.
