Title: fix for replies breaking on forum posts not associated with projects. PM...

...T #96468

Old forum posts, and posts made through the Perl version, when not
associated with a project, get a '0' as the project id for that column
instead of a NULL. Django does the right thing on creating them
and consistently sets it to NULL, but we still need to deal with the
old data for a while longer.
