Fix issue with inconsistent view regarding the job_jobresult.html page

[FloLaco]

Fixes: #864

Reproduce the same web page as job_jobresult.html (corresponding URI : extras/jobs/results/<uuid>/)

Thanks for the PR! A more ideal fix would be to merge the job_jobresult.html and jobresult.html templates into a common page, but this will need some additional conditional template logic as, for example, the breadcrumbs that we display for a generic JobResult are different than those for a Job-specific JobResult. Similarly, we'd ideally want to consolidate JobResultView and JobJobResultView as well.

So, I am also trying to tackle this in my PR for adding a model for Job Log messages. I incorporated your changes into my PR. #1030

Thank you for the PR! Since this will be addressed as part of #1030, I'm closing this one.
