Media are not always marked as local even though file is in git-annex

[agger-magenta]

Even though file is downloaded (i.e., media is local), it still has is_local=False.

I wrote this small program to run once in a while:

from media.models import Media

ms = Media.objects.filter(is_local=False, is_requested=True)
for m in ms:
    m.set_is_local()
    if m.is_local:
        m.save()

This should not be necessary, i.e. is_local should be updated when the download is done, following the request and running of process_requests.sh.
