Fix empty brackets showing in pipeline status
Hey! I noticed that sometimes the status bar would show
GitLab: Pipeline running () and I find the empty parenthesis ugly (sorry!
I suspect the parenthesis are empty because
fetchLastJobsForCurrentBranch probably returns an empty array if all jobs are pending. I'm not really sure how it happens but it did for me a couple of times now.
This MR adds a check that at least one job has to be present to append the parenthesis with the job name(s).
