HHH-19743 Default to NaranaJtaPlatform instead of JBossStandAlonePlatform when relevant

When we default to JBossStandaloneJtaPlatform,
we've already checked that WildFlyStandAloneJtaPlatform cannot be used,
so JBossStandAloneJtaPlatform is strictly equivalent to NarayanaJtaPlatform.

Since JBossStandAloneJtaPlatform is deprecated, let's use
NarayanaJtaPlatform instead.
