Shender/git118 refresh buddy text

Describe your PR
There was really 2 bugs here. The buddy text wasn't updated till the job had finished executing, thus sending a :finished SSE.
There was also a problem with the job.reload() not reading the updated values written by the thread which executed the job. This is a Rails bug that doesn't bypass the QueryCache for reloads.
