Description
Editing url to non-existent tag with tags navigation shows all content.

Steps to Reproduce
1. Create a blank site with a site page.
2. Add 3 images to the Docs and Media application for that site.
3. For each image, categorize them via tags. For two of them tag "test" and do not tag the third image.
4. Drop a media gallery display portlet on a page.
5. Drop tag navigation portlet
6. Click on the tag "test" or any tag.
7. Modify the tag param in URL and add any text e.g., product
8. Notice that the other image(s) appear.

Reproduced on:
6.2x: e3f8f33ac4818a434c7a0ea4986f9ced63cb3eab

The tags navigation in master has changed how the url is formed, this will be a 6.2.x unique fix.
