jenkins-hostname expects a trailing slash about jenkins.el

[noorul]

Also this assumes that host name contains protocol. For me just hostname/ does not work, I need to give http://hostname:port/. Also I think we can separate out port. If not we can re-name the variable to something like jenkins-url

You're right, I just replaces jenkins-hostname with jenkins-url variable. I think now it ok for this variable assume that it has slash in the end.
@noorul You can just port in this jenkins-url variable ( as you could in jenkins-hostname before). I guess now it more clear and predictable behaviour ( to have everything protocol, domain and port at the same place)

Since somebody already have installed this package I left things as backward compatible and will replace them as some point in future.
Thanks, for finding this issue. @brcm-ruperts @noorul
