This commit makes sure that JMS and Mail JNDI lookups behave the same
way as DataSource JNDI lookups by enabling the "resourceRef" flag.
This will make sure to add "java:comp/env" to the lookup if the JNDI
name doesn't already contain it. If that name does not exist, a second
attempt to the original name will be issued automatically.
Closes gh-12803
