Rollback transactions in case if Exception was thrown

[raderio]

At the moment a transaction is rollback only if it was thrown a RuntimeException.

In Kotlin there is no checked exceptions, so compiler to do not force to check when is was thrown an Exception.
When some library from Java throw an Exception, in Kotlin methods with @Transactional annotation do not rollback.

The quick-fix is to use @Transactional(rollbackFor = [Exception::class]) instead of @Transactional.
But it will be better to handle this by default in Spring.
