`fsm_log_by` decorator does not persist `by`

[jlost]

model:

@fsm_log_by
@transition(field=status, source=Status.PENDING_CODE_REVIEW.name, target=Status.CODE_REJECTED.name)
def reject_code(self, by=None):
        print('REJECTING...')
        print(by.id)
        pass

(Successfully prints user's id but doesn't persist by to StateLog)

views.py:

def post(self, request, job_id):
     job = get_object_or_404(Job, pk=job_id)
     if not can_proceed(job.reject_code):
          raise PermissionDenied
     job.reject_code(self.request.user)
     job.save()

DB:

postgres=# select * from django_fsm_log_statelog;
 id |           timestamp           |     state     |  transition  | object_id | by_id | content_type_id

REPL:

>>> StateLog.objects.get(pk=6).by
>>> StateLog.objects.get(pk=6).by_id

This is with the latest pip release, 1.5.0

Found my obvious rookie mistake -- passing in the user as an arg rather than kwarg.

Fix: job.reject_code(self.request.user) -> job.reject_code(by=self.request.user)
