Fix Error 500 resulting when loading network graph

discussion_id may not be present when the SELECT call for notes does not include this attribute. Don't attempt to set the discussion ID unless the model contains the attribute:

irb(main):019:0> notes[0]
  Note Load (10.3ms)  SELECT notes.commit_id, count(notes.id) as note_count FROM "notes" WHERE "notes"."project_id" = $1 AND (noteable_type = 'Commit') GROUP BY notes.commit_id  [["project_id", 13083]]
ActiveModel::MissingAttributeError: missing attribute: discussion_id

Hi, Will simple pull of 8.11 stable apply the fix to our current installation? If not what are the proper steps?

Thank you

Hi @alioozgur, if you have installed GitLab from source pulling the stable branch should fix the issue otherwise we're going to release the RC7 package today with the fix.

@rdavila thank you. I'll pull 8.11 stable tomorrow and hope that works.
