The return link for any versions open from "Roadmap" tab is "return to all versions"

Steps to Reproduce:
1. Launch JIRA 4.0
2. Click on "Browse Project" and select any project which has some versions associated with it.
3. Click on "Roadmap" tab and click on any versions.

Result:
1. All the information related to that version is shown(as clicking from version tab)
2. The upper link says "Return to all versions" whereas clicking on takes user back to "Road Map" tab. Hence it can be confusing.

Expected:
1. The link should be clear and informative
