quick fix to allow users' query.
various workflow refactor

1 defer interviewer's selection until interview creation
2 cleanup the interview page, now we assume that the partial 'interviews/_form.htlm.slim' is only loaded
  after opening is already fixed or selected by user.
3 use 'default_scope' for active users' retrieval
