Discover presence of UI before jack_activate

jalv.has_ui should be set before jack_activate. If not, patch:Get message
may be without effect and parameter replies never be sent from within jack
process callback, as the latter may run before the corresponding UI logic
(e.g. with jalv.has_ui still being false).
