Allow JPA bytecode enhancement to work with applications using java:comp/DefaultDataSource

To recreate problem, run:

cd wildfly/testsuite/integration/basic

1. update persistence.xml to <property name="jboss.as.jpa.classtransformer" value="true"/>
   vim src/test/java/org/jboss/as/test/integration/jpa/webnontxem/persistence.xml
   mvn clean install -Dtest=org.jboss.as.test.integration.jpa.webnontxem.NonTransactionalEmTestCase

Test deployment failure can be found in the server.log, something like:
