Hudson 1.73

On the frontpage of a project where tests are included, you have a test graph.
If you click on the "enlarge" link underneath it, it will enlarge the graph. In
this enlarged view, the "Build Time Trend" link doesn't work, but gives a 404 error.

This is caused by the fact that the trend-link is relative, and just appends
/buildTimeTrend to the URL.

example:
http://localhost:8080/hudson/job/myproject/
http://localhost:8080/hudson/job/myproject/test/?width=800&height=600
http://localhost:8080/hudson/job/myproject/test/buildTimeTrend <== 404 error==>
http://localhost:8080/hudson/job/myproject/buildTimeTrend <== OK ==>
