[web2py] db.mytable(myid) syntax throws exception for GAE in 1.86.2

[robe...@captivation.com]

It boils down to this:

    record = self._db(self._id == id).select(limitby=(0,1)).first()
  File \"/Users/robertm/backbeat/backbeat/3rd/web2py/gluon/sql.py\",
line 1683, in __getattr__
    return dict.__getitem__(self,key)
KeyError: '_id'

I think the issue is that gql.py Table.__init__ does not set self._id
as sql.py Table.__init__ does

Cheers,
