serviceDiscoveryType false doesn't work

[deepu105]

Seems like recent changes to make false work with serviceDiscoveryType instead of no is broken.

application {
  config {
    baseName store,
    applicationType gateway,
    packageName com.jhipster.demo.store,
    serviceDiscoveryType false,
    authenticationType jwt,
    prodDatabaseType mysql,
    cacheProvider hazelcast,
    buildTool gradle,
    clientFramework react,
    useSass true,
    testFrameworks [protractor]
  }
}

produces
