Fix quick searching for group with spaces on name

How to reproduce

• go to JSF UI
• create a new group giving a name like "nuxeo workers" and a label with "nuxeo", add some users to the group
• go to quick search for the group label or name, click when it appears
• page not found error - bug

This only happens in JSF UI and with groups with names with spaces

example of a link for the page not found: https://nxdev-dev01-11.beta.nuxeocloud.com/nuxeo/group/olivais%20sul?conversationId=0NXMAIN24

group name: olivais sul
group label: olivais
