cursor._session is None when iterating over cursor directly

[jmartinez-jobsity]

When running something like:

with pytds.connect(as_dict=True, **settings.mssql) as conn:
    with conn.cursor() as cursor:
        cursor.callproc(self.SP_NAME)
        for row in cursor:
            print(row)

I'm getting a 'NoneType' object has no attribute 'fetchone' from the _session being None

> /usr/lib/python3.5/site-packages/pytds/__init__.py(744)fetchone()
-> row = self._session.fetchone()
(Pdb) self._session is None
True

For now, the workaround is to iterate over cursor.fetchall(), but I think iterating over the cursor directly should not raise that exception

Can you provide full stack trace? Also can you test it on current tip of master branch?

Seems to be fixed now
