SchemaUtils.create doesn't use enum column's 'toDb' function

[terminalnode]

Using Kotlin 1.6.10 and Exposed 0.37.3

When setting a default value for an enum column and using SchemaUtils.create, Exposed uses toString() instead of the toDb method.

Here's as small an example as I could come up with to recreate the issue:

object MyTable : LongIdTable(name = "my_table", columnName = "id") {
  val myEnum: Column<MyEnum> = customEnumeration(
    name = "my_enum",
    sql = "ENUM('${MyEnum.DEFAULT.dbString}')",
    fromDb = { MyEnum.values().first { e -> e.dbString == (it as String) } },
    toDb = { it.dbString }, // <-- this and the line below are the relevant parts
  ).default(MyEnum.DEFAULT)
}

enum class MyEnum(val dbString: String) {
  DEFAULT("the default value");
  override fun toString() = "the wrong string!"
}

fun main() {
  Database.connect(
    url = "jdbc:mysql://localhost:3306/test",
    driver = com.mysql.cj.jdbc.Driver::class.qualifiedName!!,
    user = "username", password = "password")

  transaction {
    SchemaUtils.create(MyTable)
  }
}

This will generate the following SQL:

CREATE TABLE IF NOT EXISTS my_table (id BIGINT AUTO_INCREMENT PRIMARY KEY, my_enum ENUM('the default value') DEFAULT 'the wrong string!' NOT NULL)

which throws the following exception:

org.jetbrains.exposed.exceptions.ExposedSQLException: java.sql.SQLSyntaxErrorException: Invalid default value for 'my_enum'
