run-tests: stop explicit expansion of time data

We are about to record more complex time related data, this would requires
repeated changes of every loop touching times data. That would also extend such
line to a point were things become too long. Instead we iterate on each entry
and expand value in the loops. We keep intermediate variables in most case to
preserve readability.

The loop producing json data do a strange inversion for no obvious reason. We
preserved that for now and will fix it in another changeset.
