When migrating a legacy JBoss Web subsystem configuration, which includes an SSL connector, the security realm, referenced by the resulting Undertow subsystem configuration, is not created if the migrate: op is invoked by a standalone embedded process.

The concrete issue is that the migrate: op logic, as expected, is different wether the process type in context is wrt a managed domain configuration or not, but it wrongly considers any ProcessType that is not STANDALONE or SELF_CONTAINED as managed domain, applying the wrong logic to process types such as EMBEDDED_SERVER.
