Nullpointer bug in HeritrixController.java

harvester/heritrix3/heritrix3-controller/src/main/java/dk/netarkivet/harvester/heritrix3/controller/HeritrixController.java

In cleanup() line 352:

if (jobResult.job.crawlControllerState != null)

jobResult.job can be null. Needs a test for not null also.

We got a nullpointerexception on that line, which led to that NAS crashed and started a new crawl on that instance, which failed ("Port 9290 already in use").

Version 7.3 (21bc5d6b60)

(Updated copy of [https://github.com/netarchivesuite/netarchivesuite/issues/116
] Maybe should close issue-service there, or link her? Or can both be used?)
