Fix duplicate UI initialization

Browse Source 
When loading the very first session is canceled (e.g.
sample-rate mismatch -> Do not load session) or fails otherwise,
execution returns to the startupFSM.

Loading another session after that then takes the same path again:

StartupFSM::dialog_response_handler() -> StartupFSM::engine_running()
-> ARDOUR_UI::attach_to_engine()

The call needs to be idempotent, otherwise setup_windows(),
create_editor() etc are called a second time and Ardour crashes.
