Some projects on Grouped runs page throws error and cannot display data on Jobs table

[Mohan Seri]

Open health dashboard and click on openstack/tempest project from Projects ( http://status.openstack.org/openstack-health/#/g/project/openstack~2Ftempest ) and notice that the data is not being displayed in Jobs table due to the below API error:

GET http://health.openstack.org/runs/key/project/openstack/tempest?datetime_resolution=hour&start_date=2018-07-24T04:00:00.000Z&stop_date=2018-08-07T04:00:00.000Z&callback=angular.callbacks._4 500 (Internal Server Error)

    fix prepare for numeric data

    There is a case where there can be more than one build_name
    with the same run_at[1] and without this change the request in [1]
    will result in a KeyError[2]

    The run_aggregator method is now updated to work with runs with
    more than one build_name so that the expected_responses from
    the unit tests make more sense and it makes it more ready to be
    used for displaying run times in the grouped runs page.
