The build queue graph in Jenkins does not properly show jobs which are in the queue when the job is using the node label parameter.

To reproduce:

• create a label in Jenkins called LabelX
• create a job which contains a nodelabel parameter and give it the value "LabelX". Make sure that the job can run concurrently and that the option "Restrict where this project can be run" is not clicked.
• execute enough instances of the job so that there are some jobs in the build queue
• click LabelX and then click on load statistics

Expected: the queued jobs should be represented in the graph with the grey line

Actual: the queued jobs are not displayed properly in the graph
