The link to a run's hosted report was in the job summary, the Markdown report and Slack, but not in the CI log. donobu test now prints it as its last line, after uploads finish:
donobu test: full report at https://donobu.com/home//test-runs/
DONOBU_REPORT_URL still overrides the link. Without cloud results, nothing is printed.
A link to a run nobody has opened yet now always finds it, even on accounts with many runs.
