Cannot import clients if there is a client with Authorization enabled.

If there is a client with Authorization enabled, importing clients is failed as follows.

16:49:50,883 FATAL [org.keycloak.services] (ServerService Thread Pool – 54) Error during startup: java.lang.RuntimeException: Script upload is disabled

This does not depend on whether importing it from the admin console or not.

When setting "-Dkeycloak.profile.feature.upload_scripts=enabled", the import succeeds, but this workaround is usually not acceptable.
