Unexpected and incorrect `is too large for column` error

Setup:
```sql
use db;
CREATE TABLE `django_session` (
`session_key` varchar(5) PRIMARY KEY
);
SELECT * FROM django_session WHERE (session_key = '0123456789');```

MySQL response is no data, but also no errors.

Dolt response:
```txt
SELECT * FROM django_session WHERE (session_key = '0123456789') LIMIT 21: string '0123456789' is too large for column 'varchar(5)'
string '0123456789' is too large for column 'varchar(5)'
```

Two problems:
1. Dolt throws an error, while MySQL does not
2. The Dolt error does not include the actual name of the column

Also, it looks like this is only a problem for primary keys. If you remove `PRIMARY KEY` from the table definition, both dolt and MySQL return no data and no errors.
