In Jenkins 1.454, the copy project link plugin does not work when copying a job which is using the new 'display name' feature.

You can repro with these steps:

• create job A and go to the configure page.
• click the Advanced... button next in the 'Advanced Project Options section.
• set the Display Name to something like 'My job'
• save the config page
• on the main job page, click the 'Copy project' link to copy it
• note the URL has the (internal) job name – 'A' (good)
• enter a new job name, and click OK.

At this point, you get an error message of the form:

Error
No such job: My job

A workaround is to use the normal 'new job' approach for copying a job.
