Reporting call to getDefaultProvenaceRecorder occasionally gets an NPE
Sometimes when you execute a workflow in WRP, you'll get an NPE from Reporting when it calls ProvenaceRecorder.getDefaultProvenaceRecorder. I think this may be related to changing the report and rerunning the workflow but I'm not sure...

Now I think this happens when you make a change to certain workflows and an entirely new lsid is gotten, and the old one is placed in the derived from list, instead of just bumping the revision. I'm not sure of all the cases in which this occurs (it seems like this sometimes happens when it shouldn't, but that would be a separate issue), but one is when you rename the workflow. When a new lsid is assigned to the workflow, the call to get the workflow out of ObjectManager in getProveanceRecorder returns null, even though the new lsid is used:
NamedObj reference = ObjectManager.getInstance().getHighestObjectRevision(lsid);
