#399 Null pointer exception on closing QA window

[Kirti Chennareddy]

Tested on DPR 5.0.8 on Ubuntu
Closing the QA window in PF stage using the x button rather than using cancel or done button throws a null pointer exception error,(See attached screen shot)
java.lang.NullPointerException
at au.gov.naa.digipres.dpr.task.step.QualityAssuranceStep.doProcessing(QualityAssuranceStep.java:149)
at au.gov.naa.digipres.dpr.ui.task.StepProcessingThread.run(StepProcessingThread.java:87)

Steps to reproduce:
Log in to DPR-PF
Process a transfer job
At the Quality assurance step, it will open the QA window.
Click on x to close the window
