If you click on periodic jobs in prow, we get the following internal service error

Look at the code in view_build.py

        refs = []
        if started and 'pull' in started:
            for ref in started['pull'].split(','):
                x = ref.split(':', 1)
                if len(x) == 2:
                    refs.append((x[0], x[1]))
                else:
                    refs.append((x[1], '')

If we look at started.json

gsutil cat gs://kubernetes-jenkins/logs/mlkube-build-periodic/32/started.json
{"timestamp": 1508781634, "repos": {"jlewi/mlkube.io": "a1d0405d0941f5b10addb7548f8a8a596a917472"}, "pull": ""}

So the problem appears to be that we shouldn't set the pull entry to the empty string in started.json

[jlewi]

Still not fixed.

gsutil cat gs://kubernetes-jenkins/logs/mlkube-build-periodic/34/started.json
{"timestamp": 1508839343, "repos": {"jlewi/mlkube.io": "3e19cf5f9b58be5e5c537389e1ba9e1ed1120714"}, "pull": ""}

So "pull" is still there.
