Invalid many2many encoding in test_orm.py

[Stefan Rijnhart (Opener)]

I'm suggesting the following change to fix an exception occuring in the test suite:

- self.uid2 = self.users.create(cr, uid, {'name': 'test user', 'login': 'test', 'groups_id': [4,employee_gid]})
+ self.uid2 = self.users.create(cr, uid, {'name': 'test user', 'login': 'test', 'groups_id': [(4,employee_gid)]})
