Bad foreign key error message

[bheni]

steps:

~/datasets>mkdir bug
~/datasets>cd bug
~/datasets/bug>dolt init
Successfully initialized dolt data repository.
~/datasets/bug>echo 'CREATE TABLE x (
>   id int PRIMARY KEY NOT NULL
> );
>
> CREATE TABLE y (
>   id int PRIMARY KEY NOT NULL
> );
>
> ALTER TABLE x ADD COLUMN x_id_fk int;
> ALTER TABLE x ADD FOREIGN KEY (x_id_fk) REFERENCES x(id) ON DELETE RESTRICT;
> ALTER TABLE x DROP COLUMN x_id_fk;' | dolt sql

output:

error on line 11 for query
ALTER TABLE x DROP COLUMN x_id_fk: cannot drop column `x_id_fk` as it is used in foreign key `10069`
cannot drop column `x_id_fk` as it is used in foreign key `10069`

Looks like this is consistent with MySQL's behavior. Here's what I get against MySQL:

mysql> ALTER TABLE x DROP COLUMN x_id_fk;
ERROR 1828 (HY000): Cannot drop column 'x_id_fk': needed in a foreign key constraint 'x_ibfk_1'

Still a bug here, which is that the error message doesn't name the constraint (looks like it's using a tag value?)
