SWITCHYARD-1860 TransactionSynchronizationRegistry doesn't work on TransactionMixIn

Reported by tschan+redhat.com@devzone.ch

TransactionSynchronizationRegistry has JTS version of TransactionManager in its field by default, causes initialization error since ORB doesn't exist. Using jtaPropertyManager.getJTAEnvironmentBean() and set JTA version of implementation class names instead of new JTAEnvironmentBean() avoids this problem.
