django.utils.duration.duration_string() doesn't support negative durations

Description

duration_string() formats timedeltas like this:

duration_string(timedelta(hours=1))
'01:00:00'

Given a negative hour, I would expect duration_string() to return something like "-01:00:00". Instead, you get this:

duration_string(timedelta(hours=-1))
'-1 23:00:00'

The behavior seems consistent with str(timedelta(hours=-1)) which gives '-1 day, 23:00:00'. See ​Python's docs that explains normalization of negative values.
