get_all_pending() takes 3 positional arguments but 4 were given

Hi,

the "autoflush" feature triggers an error in SQLAlchemy 0.9.6.

  File "/opt/pas/src/dNG/pas/data/upnp/resources/mp_entry.py", line 588, in init_cds_id
    .first()
  File "/usr/lib/python3.4/site-packages/sqlalchemy/orm/query.py", line 2334, in first
    ret = list(self[0:1])
  File "/usr/lib/python3.4/site-packages/sqlalchemy/orm/query.py", line 2201, in __getitem__
    return list(res)
  File "/usr/lib/python3.4/site-packages/sqlalchemy/orm/query.py", line 2404, in __iter__
    self.session._autoflush()
  File "/usr/lib/python3.4/site-packages/sqlalchemy/orm/session.py", line 1188, in _autoflush
    self.flush()
  File "/usr/lib/python3.4/site-packages/sqlalchemy/orm/session.py", line 1907, in flush
    self._flush(objects)
  File "/usr/lib/python3.4/site-packages/sqlalchemy/orm/session.py", line 2025, in _flush
    transaction.rollback(_capture_exception=True)
  File "/usr/lib/python3.4/site-packages/sqlalchemy/util/langhelpers.py", line 57, in __exit__
    compat.reraise(exc_type, exc_value, exc_tb)
  File "/usr/lib/python3.4/site-packages/sqlalchemy/util/compat.py", line 172, in reraise

TypeError: get_all_pending() takes 3 positional arguments but 4 were given

I think it's related to commit 69dbcdd which in turn is related to ~~#3060~~ as far as I understand.

Best regards Tobias
