The behavior of the MariaDB backend has changed behavior for UUIDField from a `CharField(32)` to an actual `uuid` type. This is not converted automatically, which results in all writes to the affected columns to error with a message about the data being too long. This is because the actual tring being written is a UUID with the `-` included, resulting in a 36 character value which can't be inserted into a 32 character column.
