like() Numeric bug

Im using v2.1.1

When using `.like()` and `.or_like()`  on numeric, Quote got removed '%123%' became %123% and error of execution

`ER_PARSE_ERROR: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '%123% OR `first_name` LIKE %123% OR `last_name` LIKE %123% ORDER BY `id` DESC LI' at line `
