`create_database` should not add default charset when `collation` is given
If `collation` is given without `charset`, it may generate invalid SQL. For example `create_database(:matt_aimonetti, collation: "utf8mb4_bin")`: ``` > CREATE DATABASE `matt_aimonetti` DEFAULT CHARACTER SET `utf8` COLLATE `utf8mb4_bin`; ERROR 1253 (42000): COLLATION 'utf8mb4_bin' is not valid for CHARACTER SET 'utf8' ``` In MySQL, charset is used to find the default collation. If `collation` is given explicitly, it is not necessary to give extra charset.
