Jaeger exporter was broken since commit c0dfb7d, after a time calculus change it ended up using milliseconds instead of microseconds. Replace variables names in tests so it is obvious that the microseconds is the unit, so it cannot get broken again.

Also modify another test on Datadog exporter that fails randomly on local to not fail anymore
