Use table name qualified column name for update counters
MySQL supports JOINs to UPDATE, so if column name isn't qualified by
table name, it would cause an ambiguous error:
```
Mysql2::Error: Column 'integer' in field list is ambiguous: UPDATE `pets` INNER JOIN `toys` ON `toys`.`pet_id` = `pets`.`pet_id` SET `integer` = COALESCE(`integer`, 0) + 1 WHERE `toys`.`name` = ?
```
