This is an adopted version of 8b1e071d.
Since 1.7 has a flag to disable this behaviour, I think a better fix is
to disable this flag by default.

I actually applied the diff from

This still is slightly more robust than the original in the sense that it's not affected by the presence/absence of the trailing '/' in itUrl.

Comment from @ohtake:

getContextPath() will return "" if Jenkins is served at ROOT.

Assume that getContextPath() => "", itUrl => "iturl" and urlName => "urlName",
value returned was "/iturl/urlName", but is "iturl/urlName" (no slash at 0).
