Title: [JENKINS-22683] NullPointerException in ProjectDiskUsageAction.getGraph(...

...ProjectDiskUsageAction.java:227)

* Probable scenario is to refresh the job page (the one that displays the trend graph) while a build of that job is in progress.
* Variable dua was checked for null and then dua.getAllDiskUsage() was called outside of the condition - fixed.
