Fixed #20 column_constraint REFERENCES for accepting empty column list

Description

It looks like that all tests are around either table constraints or by using references a(column). So I wrote a small test following @spencercw's concept:

create table a (
  id int identity primary key,
  texto varchar(50) NOT NULL
);

-- column_constraints
create table b (
  id int identity primary key,
  foreign_id int not null references a, -- no column specified
  texto varchar(50) NOT NULL
);
GO

SET IDENTITY_INSERT dbo.a ON;
GO

insert into a(id,texto) values(1, 'some text');
GO

insert into b(foreign_id, texto) values(1,'insert text');
GO

1> SELECT * FROM a;
2> SELECT * FROM b;
3> GO
id      texto
1       some text
(1 row affected)
id      foreign_id      texto
1       1       insert text
(1 row affected)

Tested also the FK reference functionality:

1> insert into b (foreign_id, texto) values (10,'fail?');
2> GO
Msg 547 (severity 16, state 1) from BABELFISH Line 1:
        "insert or update on table "b" violates foreign key constraint "b_foreign_id_fkey""
