Regression: @Inject UserTransaction doesn't work in the SwitchYard test case

Make sure ENTESB-3600 doesn't happen on Fuse 6.2.1.

For convenience, here is the original issue description in ENTESB-3600:
=======================================================
"@Inject UserTransaction" support, which was supposed to be introduced by SWITCHYARD-1114 in SY 1.1, doesn't seem to work as expected. When you try to test from SwitchYardRunner a Bean service that has a UserTransaction field @Inject'ed like this:

    @Inject
    private UserTransaction ut;

the test throws the following error and fails:

org.jboss.weld.exceptions.DeploymentException: WELD-001408 Unsatisfied dependencies for type [UserTransaction] with qualifiers [@Default] at injection point [[field] @Inject private com.redhat.samples.switchyard.GreetingServiceImpl.ut]
