Description

TransactionProxyRollbackOnlyImpl can throws  UnsupportedOperationException to user.

It is ok if objects throws such exception if someones tries to violate contract, 
but seems user can faced this exception within normal flow.
See TxRollbackAsyncTest.testRollbackProxy().

Let's fix implementation to throw correct TransactionException to user.
