FISH-5968 leave transaction intact if mentioned in unchanged parameter

[aubi]

DescriptionFixes testContextServiceDefinitionAllAttributes TCK test, method ContextService.contextualFunction() with transaction defined as this:

@ContextServiceDefinition(name = "java:app/concurrent/ContextA",
                          propagated = { APPLICATION, IntContext.NAME },
                          cleared = StringContext.NAME,
                          unchanged = TRANSACTION)

Note the unchanged = TRANSACTION -- the transaction is now unchanged.

I accidentally moved the payara6-concurrency-3.0-upgrade branch, so this diff doesn't include the main commit of this PR:
