commit b28a11761463de3e316b039675c55864667bf13f introduced NPE when deploying RA.

There is a lot of failing tests in IronJacamar testsuite, one example is org.jboss.jca.deployers.test.unit.connector16.Ra16Standard303TestCase

issue seems to be AbstractResourceAdapterDeployer.java#L1658 where connectionDefinition is null in some cases.

There are more issues similar to this one added by later commits for Elytron integration. AbstractResourceAdapterDeployer.java#L1666 will have the same problem.
